However this can be a problem when you're surfing for a long period of time (at least on windows), since HFONTs are GDI handles, of which there are only a fixed number. Turn on the GDI object column of the task manager (View->Select Columns...) and then view the attached test case, to see Safari bloat up to > 2000 GDI objects and never drop below that. 76084 1 20275 eric 2008-04-01 16:38:02 -0700 Created attachment 20275 test case 76085 2 20276 eric 2008-04-01 16:42:39 -0700 Created attachment 20276 another test case (probably hits GDI session limit) 76090 3 20279 eric 2008-04-01 17:05:02 -0700 Created attachment 20279 another test case (takes forever) 76113 4 hyatt 2008-04-01 19:05:06 -0700 This bug is a dup of one aroben filed (also in bugzilla). 76114 5 mitz 2008-04-01 19:25:00 -0700 *** This bug has been marked as a duplicate of 17097 *** 20275 2008-04-01 16:38:02 -0700 2008-04-01 16:38:02 -0700 test case lots_o_fonts.html text/html 829 eric PGh0bWw+PGJvZHk+DQo8c2NyaXB0Pg0KdmFyIGZvbnRGYW1pbGllcyA9IFsNCiAgJ0FyaWFsJywN CiAgJ1RpbWVzIE5ldyBSb21hbicsDQogICdHZW9yZ2lhJywNCiAgJ1ZlcmRhbmEnLA0KICAnVHJl YnVjaGV0JywNCiAgJ0NvdXJpZXIgTmV3JywNCiAgJ0Jvb2ttYW4nLA0KICAnR2FyYW1vbmQnLA0K ICAnQXZhbnQgR2FyZGUnLA0KICAnUGFsYXRpbm8nLA0KICAnQ29taWMgU2FucycsDQogICdJbXBh Y3QnLA0KICAnVGFob21hJywNCl07DQp2YXIgZm9udFN0eWxlcyA9IFsnYm9sZCcsICdpdGFsaWMn LCAnYm9sZCBpdGFsaWMnXTsNCnZhciBmb250U2l6ZXMgPSBbXTsNCmZvciAodmFyIHggPSAxMDsg eCA8IDEwOTsgeCsrKQ0KICBmb250U2l6ZXMucHVzaCh4KTsNCg0KZm9yICh4IGluIGZvbnRGYW1p bGllcykgew0KICB2YXIgZm9udEZhbWlseSA9IGZvbnRGYW1pbGllc1t4XTsNCiAgZm9yICh5IGlu IGZvbnRTdHlsZXMpIHsNCiAgICB2YXIgZm9udFN0eWxlID0gZm9udFN0eWxlc1t5XTsNCiAgICBm b3IgKHogaW4gZm9udFNpemVzKSB7DQogICAgICB2YXIgZm9udFNpemUgPSBmb250U2l6ZXNbel07 DQogICAgICB2YXIgc3BhbiA9IGRvY3VtZW50LmNyZWF0ZUVsZW1lbnQoJ3NwYW4nKTsNCiAgICAg IHNwYW4uc2V0QXR0cmlidXRlKCJzdHlsZSIsICJmb250OiAiICsgZm9udFN0eWxlICsgIiAiICsg Zm9udFNpemUgKyAicHggIiArIGZvbnRGYW1pbHkpOw0KICAgICAgc3Bhbi5pbm5lclRleHQgPSAi YSAiOw0KICAgICAgZG9jdW1lbnQuYm9keS5hcHBlbmRDaGlsZChzcGFuKTsNCiAgICB9DQogIH0N Cn0NCjwvc2NyaXB0Pg0KPC9ib2R5PjwvaHRtbD4NCg== 20276 2008-04-01 16:42:39 -0700 2008-04-01 17:05:02 -0700 another test case (probably hits GDI session limit) lots_o_fonts.html text/html 833 eric PGh0bWw+PGJvZHk+DQo8c2NyaXB0Pg0KdmFyIGZvbnRGYW1pbGllcyA9IFsNCiAgJ0FyaWFsJywN CiAgJ1RpbWVzIE5ldyBSb21hbicsDQogICdHZW9yZ2lhJywNCiAgJ1ZlcmRhbmEnLA0KICAnVHJl YnVjaGV0JywNCiAgJ0NvdXJpZXIgTmV3JywNCiAgJ0Jvb2ttYW4nLA0KICAnR2FyYW1vbmQnLA0K ICAnQXZhbnQgR2FyZGUnLA0KICAnUGFsYXRpbm8nLA0KICAnQ29taWMgU2FucycsDQogICdJbXBh Y3QnLA0KICAnVGFob21hJywNCl07DQp2YXIgZm9udFN0eWxlcyA9IFsnYm9sZCcsICdpdGFsaWMn LCAnYm9sZCBpdGFsaWMnXTsNCnZhciBmb250U2l6ZXMgPSBbXTsNCmZvciAodmFyIHggPSA4OyB4 IDwgMjAwOyB4ICs9IDAuMSkNCiAgZm9udFNpemVzLnB1c2goeCk7DQoNCmZvciAoeCBpbiBmb250 RmFtaWxpZXMpIHsNCiAgdmFyIGZvbnRGYW1pbHkgPSBmb250RmFtaWxpZXNbeF07DQogIGZvciAo eSBpbiBmb250U3R5bGVzKSB7DQogICAgdmFyIGZvbnRTdHlsZSA9IGZvbnRTdHlsZXNbeV07DQog ICAgZm9yICh6IGluIGZvbnRTaXplcykgew0KICAgICAgdmFyIGZvbnRTaXplID0gZm9udFNpemVz W3pdOw0KICAgICAgdmFyIHNwYW4gPSBkb2N1bWVudC5jcmVhdGVFbGVtZW50KCdzcGFuJyk7DQog ICAgICBzcGFuLnNldEF0dHJpYnV0ZSgic3R5bGUiLCAiZm9udDogIiArIGZvbnRTdHlsZSArICIg IiArIGZvbnRTaXplICsgInB4ICIgKyBmb250RmFtaWx5KTsNCiAgICAgIHNwYW4uaW5uZXJUZXh0 ID0gImEgIjsNCiAgICAgIGRvY3VtZW50LmJvZHkuYXBwZW5kQ2hpbGQoc3Bhbik7DQogICAgfQ0K ICB9DQp9DQo8L3NjcmlwdD4NCjwvYm9keT48L2h0bWw+DQo= 20279 2008-04-01 17:05:02 -0700 2008-04-01 17:05:02 -0700 another test case (takes forever) lots_o_fonts.html text/html 1091 eric PGh0bWw+PGJvZHk+DQo8c2NyaXB0Pg0KdmFyIGZvbnRGYW1pbGllcyA9IFsNCidBcmlhbCcsDQon QXJpYWwgQmxhY2snLA0KJ0NvbWljIFNhbnMnLA0KJ0NvdXJpZXInLA0KJ0NvdXJpZXIgTmV3JywN CidFc3RyYW5nZWxvIEVkZXNzYScsDQonRnJhbmtsaW4gR290aGljIE1lZGl1bScsDQonR2F1dGFt aScsDQonR2VvcmdpYScsDQonSW1wYWN0JywNCidMYXRoYScsDQonTHVjaWRhIENvbnNvbGUnLA0K J0x1Y2lkYSBTYW5zIFVuaWNvZGUnLA0KJ01TIFNhbnMgU2VyaWYnLA0KJ01TIFNlcmlmJywNCidN aWNyb3NvZnQgU2FucyBTZXJpZicsDQonTW9kZXJuJywNCidNdiBCb2xpJywNCidQYWxhdGlubyBM aW5vdHlwZScsDQonUm9tYW4nLA0KJ1NjcmlwdCcsDQonU21hbGwgRm9udHMnLA0KJ1N5bWJvbCcs DQonVGFob21hJywNCidUaW1lcyBOZXcgUm9tYW4nLA0KJ1RyZWJ1Y2hldCcsDQonVHVuZ2EnLA0K J1ZlcmRhbmEnLA0KJ1dTVF9DemVjaCcsDQonV1NUX0VuZ2wnLA0KJ1dTVF9GcmVuJywNCidXU1Rf R2VybScsDQonV1NUX0l0YWwnLA0KJ1dTVF9TcGFuJywNCidXU1RfU3dlZCcsDQonV2ViZGluZ3Mn LA0KJ1dpbmdEaW5ncycNCl07DQp2YXIgZm9udFN0eWxlcyA9IFsnYm9sZCcsICdpdGFsaWMnLCAn Ym9sZCBpdGFsaWMnXTsNCmZvciAoeCBpbiBmb250RmFtaWxpZXMpIHsNCiAgdmFyIGZvbnRGYW1p bHkgPSBmb250RmFtaWxpZXNbeF07DQogIGZvciAoeSBpbiBmb250U3R5bGVzKSB7DQogICAgdmFy IGZvbnRTdHlsZSA9IGZvbnRTdHlsZXNbeV07DQogICAgZm9yICh2YXIgZm9udFNpemUgPSA4OyBm b250U2l6ZSA8IDIwMDsgZm9udFNpemUgKz0gMC4wMSkgew0KICAgICAgdmFyIHNwYW4gPSBkb2N1 bWVudC5jcmVhdGVFbGVtZW50KCdzcGFuJyk7DQogICAgICBzcGFuLnNldEF0dHJpYnV0ZSgic3R5 bGUiLCAiZm9udDogIiArIGZvbnRTdHlsZSArICIgIiArIGZvbnRTaXplICsgInB4ICIgKyBmb250 RmFtaWx5KTsNCiAgICAgIHNwYW4uaW5uZXJUZXh0ID0gImEgIjsNCiAgICAgIGRvY3VtZW50LmJv ZHkuYXBwZW5kQ2hpbGQoc3Bhbik7DQogICAgfQ0KICB9DQp9DQo8L3NjcmlwdD4NCjwvYm9keT48 L2h0bWw+DQo=
