In an attempt to stop the thousands of mail messages flooding UCSD and the
internet because of a mail loop through USL.EDU's news system, I am going
to disable all tcp-group mail for a day or so.  Mail sent to tcp-group
during that time should bounce back for 'address unknown'.

Gee, i thought this was something we 'NOS users' (as opposed to
developers, i guess) just had to live with ! I've been running a
minimized version of PA0GRI's 2.0m for months, just using the asy
driver to a 9600 baud TNC and it ROUTINELY gets crashed by over
zealous pingers testing the 9600 baud repeater system. Generally,
it appears that NOS sucks up all the available memory, then dies.
Seems like there is more than the pktdrvr at fault here.
