pthreads has been a sore point for a long time.  However, I think
those days might be over.  *cross fingers*

Grab the latest 'n' greatest bproc from CVS on sourceforge.net.  It's
got a lot of fixes for threading related stuff in there.  I think I'm
going to have a tagged version again pretty soon.  Also, make sure
that you're using NPTL and not the old linuxthreads stuff.  I've done
testing with NPTL only at this point.  If linuxthreads doesn't work
I'm prepared to say "use NPTL".

Note that you can't migrate a multithreaded thing at this point.  The
result of that is undefined.
