WebCore never releases GDI font handles (HFONTS) WebCore (I think by design) never releases font objects. 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.
