Gah.  Just Gah.

However...  my current build of svn with 5.4_PRERELEASE
kernel/userland passes all but 10 tests.  7 of those are related to
SIGFPE needing a working handler, and the rest are NullReference
exceptions.  Both of these can be fixed and work against -lpthread,
and sigcontext (I think) for older BSD systems.

Your test code which simply invokes Process.Start('ls') also crashes
on my build, though - apparantly due to the same threading problems
discussed by Xu in his excellent analysis.  I wonder, naively of
course, if it may somehow be possible to provide a working
Process.Start without a complete migration (and prerequisite for)
-CURRENT 6.x and __thread/-lthr.

I'll look more at it later, but this is quickly going over my (now
exploded) head  too.
