Neither signal handling (which includes reaping child processes when
they exit) nor memory management is thread-safe, and there may be
shared memory issues with threads and traditional process forking as
well.  The more threads you try to have the more likely you're going
to be to wander into one of these areas.  I'd be very skeptical that
you can just plop threading into one part of zsh without at least some
serious semaphore work on the rest of it.
