Nah, in those kinds of cases trn 4.0 test72 just hangs (kill -9 needed)
for me; I don't seem to experience absurdly high article numbers in those
cases.   Using my crappy ISP newsserver I've experienced trn lockups
because of crashed connection a few dozens of times, but not a single
time 'absurdly high article numbers'...

Well, I seem to remember once telnetting to a newsserver and getting
too high article numbers in response to a GROUP <newsgroup>, so maybe
our problems are not exactly the same...
I think I'll compile test76 or CVS with DEBUG turned on and run a while
like that to see if that results in useful info.

Yeah, I agree: trn for reading and posting text messages and downloading
binaries (with nget as backup for quirky servers etc.) and my own shell
script for posting binaries is all I need for usenet. :)
