I'll check that out, but we were talking about a delivery problem here,
and a delivery process has done a re-exec on the Exim binary, so the
signal handlers should have all been reset.

Hmm. There are some non-standard configurations where the re-exec does
not happen. Mike, can you confirm that you are running a "standard" type
of configuration? (exim setuid to root, for example).
