MailScanner processes die and don't restart

[Julian Field]

I have done some work on fixing this in the most recent versions, as this
was proving to be a problem with Postfix. If the child processes didn't die
nicely, they weren't being re-spawned. They now re-spawn regardless of how
they die. That should have fixed this problem.
