There is.
My concern is that the "scoring" might be more expensive than using the
external script?
It is about twice as slow, but the pure shell script got a LOT faster thanks to
your awk… so twice as slow is still a lot faster than what I started with.
Still, read ahead.

I figured this might be because LINEBUF is too small, but I added a
LINEBUF=20480 (and a LINEBUF=204800) to the top of the counter.rc file and got
the same error.
Since 100+ unread messages is pretty normal for me first thing in the morning,
and then again in the early evening, I'm sticking with the shell script for now.
