The man page for setjmp and longjmp should indicate whether
they are MT-safe.  They *should* be MT-safe, because they
are system calls; the kernel handles locking for you,
as least only with respect to *those* two system calls.

I say this not having read the man page for setjmp and
longjmp, so take it with a grain of salt.  If I contradict
the man page, I'll happily stand corrected.
