Thanks for the testing. I had a nasty feeling this wouldn't
be the only problem, which is why I didn't propose that patch
as a real fix.

(I think that running multithreaded programs under user-mode
emulation is effectively hitting a lot of the same locking issues
that you would get for emulating an MP core in multiple threads.)
