Mac Debug EWS bots have started to all freeze, this already happened twice in two days.
We must have made a change in WebKit that kills graphics, as the problem is that WindowServer hangs.

It is also possible that we haven't landed anything yet, and it's the patch in bug 156689 that kills EWS machines.
Alexey Proskuryakov
Looks like that was indeed it, and fixing that patch made the problem stop.
