There is already ThreadingNone.cpp - and since it's behind ENABLE(SINGLE_THREADED), I expect it to be present in your port. So, the explanation in ChangeLog is misleading.

The reason tryLock() in ThreadingNone.cpp returns false is that we have lots of assertions of this form: ASSERT(!m_databaseGuard.tryLock()).

So, even while yield() can just be added to ThreadingNone.cpp, changing tryLock() to support the logic in this function is more involved. Perhaps the approach in this patch is the right one. David, what do you think?
