6.4.3 and threaded RTS problems

Hi Folks,
Roman Leshchinskiy and I looked into the 6.4.3 crashes on Sparc/Solaris
yesterday. I think we may have found the problem, and it seems likely that this
is the same problem affecting 6.4.3 on MacOS X. The threaded RTS is assuming in
a couple of places that pthread_cond_wait() doesn't spuriously wake up, which is
apparently the case on Linux but not true in general.
I don't think this bug affects 6.6. I could be wrong, however. Does anyone on
MacOS X have a recent testsuite run with the HEAD?
I'll try to put together a fix for 6.4.3 when the 6.6 release cycle has died down.
Cheers,
Simon
