Re: 6.4.3 and threaded RTS problems

Could someone on MacOS X try the 6.4.x branch again? I just committed a fix that makes the threaded RTS more stable on Solaris, and I'm hoping it clears up the problems on MacOS X too. Remember to re-enable -threaded in ghc/compiler/Makefile if you previously disabled it.

The problem seems to be solved now, great work! Cheers, Wolfgang
