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.
