Stephan Uphoff has been working on fixing some threading kernel bugs,
and improving the pthread + SMP case. I have checked in his changes.

With these changes, I have been unable to crash the kernel in the
pthread + SMP case, running xmms and Mozilla Firebird as tests
(it used to crash pretty quickly). Some other problems should also
be gone, like threaded applications locking up.

I don't think all problems have been fixed, but it's a large step
forward. So if you've had pthread-related crashes (espcially with
SMP systems), please update your sources, and rebuild.
