Not for qmail, it doesn't. In the unlikely event that corruption
would occur, qmail-local sleeps two seconds and tries again. At that
point, the pid is still the same and the time is different.
How exactly would qmail-local (which started at T+900 milliseconds) know
that it needs to do that; when at T+700 milliseconds an app moved a file
carrying the same filename from new to cur, and THAT file was delivered to
new by another qmail-local process that had the same pid, but which exited
at T+500 milliseconds?
