        True, but the situation doesn't improve much when you have two
processes fighting over the same unwind list, either. :)  I'm not sure how
one does cross-process locking (/tmp/dynamic-unwind-<remote-pid>?), but
I'm sure I don't have time to implement it.

        Anyway, it's something I wouldn't have thought of, and I'm glad
you let me know.  It may just stew on my "known problems" list for a
while, but that's OK.
