Agreed, we (worker folks) should go investigate this further - it sounds
like we may be getting lucky and we have a platform that can repro the crash
I just wanted to mention that the main thing in the system that exercises
the platform-specific thread/locking infrastructure is workers. If there are
any synchronization bugs on a platform (or in a specific part of WebKit)
they'll primarily show up as failures in Worker tests. I don't think that's
what is happening here, but it's something to keep in mind.
