In answer to some of Paul Vixie's comments:

UUNET has handled 70 to 80 simultaneous NNTP feeds and 900 UUCP
neighbours under C News without melting any machines.

Those things don't happen to C News machine at UUNET and don't in general
happen to well-run machines.  But we've been over this before.

It's even worse in SunOS-land, but that's going to have to be fixed
eventually.  Warping and twisting every application is not the right
answer.
