I'd suggest (a) opening a separate bug in the bugzilla and (b)
getting output from "strace -fo TRACE -p PID" of a process
turning into a zombie.

Since I'm using MIMEDefang which loads the SA libraries directly, I'm
not running spamd. I'll see if tracing the multiplexor process shows
anything, though...

Sadly, I don't see much, since as soon as the process receives a TERM
signal strace disconnects:
32358 read(0, "", 4096) = 0
32358 exit_group(0) = ?
