Description Maciej Stachowiak 2010-07-15 03:56:46 PDT 
WebKitTestRunner and WebProcess simultaneously stall in CoreIPC::Connection::sendOutgoingMessage. This can be reproduced running WebKitTestRunner on the following tests:

fast/frames/cached-frame-counter.html
fast/frames/sandboxed-iframe-navigation-parent.html

Both processes appear to be trying to send each other a mach message and are stuck.
