Exactly, but every time I try to optimize much more than that, I don't
seem to get the same results.  Of course, I think I only stared at the
script for a total of maybe 15 minutes so far.  :-)

Slurping everything into an array just made it simpler to use grep()
on the array later.  Unfortunately, using grep() on *every* line made
the script a couple of orders of magnitude slower than it needed to
be...  (At the moment, /var/log/maillog* on the mail server here is
over a quarter million lines.)
