Description Maciej Stachowiak 2010-07-15 03:53:16 PDT
On the following tests, WebKitTestRunner goes crazy, using more than 100% CPU apparently handling a flood of mach messages:

fast/block/basic/min-pref-width-nowrap-floats.html
editing/style/5017613-2.html
fast/forms/input-appearance-focus.html

Sample of WebKitTestRunner

Attached a sample of WebKitTestRunner while it is in this spinning state. This is easily reproducible running WebKitTestRunner on one of the tests by hand.
