GHC 6.4.3 is stalled

[Simon Peyton-Jones]

Folks

GHC 6.4.2's threaded runtime system does not work right on 
	Solaris
	MacOSX
	Possibly FreeBSD

We'd love to fix these bugs and release 6.4.3, but we are stalled
because we don't have easy access to these platforms, nor do we have
detailed expertise in their intimate details (which is where the bugs
will be lurking).

If you care about these platforms, would you like to lend a hand?  We
probably need more help than simply "here's access to the platform", but
we'd give you very strong support if you were willing to look into it.

Failing that, I think we'll have to stick with 6.4.2.  (And the same
bugs may well show up in GHC 6.6, which we hope to release before ICFP.)
