Oh, you're right.

I think signals are probably a bad way of handling this inter- process communication. How about using a pipe? I've attached a patch
that seems to work.

It would have been possible to also set up the signal handlers before
the forking, but on OS X I seem to be getting the SIGCHLD signal
before the SIGTERM.. So I changed the code to use a pipe: http://hg.dovecot.org/dovecot-1.1/rev/635a988626d0
