Just to make sure I understand, this is only a problem if you are using
the *same* signal from two threads concurrently.  This is what I've
thought, but the phrase *If you're using a signal* makes me want to
check.  Not trying to nit-pick, just trying to make sure there isn't
some situation I don't understand.
