yes ... This is true of many of the "older" UUCP's.  if you've got sources
it's real easy to fix (It's a constant in one of the .h files).  If you
don't got sources ... welll ...



Another way around this is to make rnews a one line script like:

	cat >/usr/spool/some-dir/uunews.$$
	exit 0

Then you have another shell script like:

	cd /usr/spool/some-dir
	for i in uunews*; do
		if /usr/lib/news/real-rnews <$i; then
			rm -f $i
		else
			mv $i P.$i
		fi
	done

I've always run this using "flock" to make sure that only one of these
guys is running at a time.  "flock" is more intelligent than the
locking mechanism in uuxqt...

The only thing I can say about hanging-on-checkgroups is that it's
never hung here.  It's usually come up with a really strange message,
but it's never hung.

Oh, that deal in the script about checking the exit status from real-rnews
and mv'ing the file to P.$i really helps a lot ... but then we have
news coming in from many strange paths.  Anyway, I just go look for P.
files from time to time ...
