I noticed eons ago (NetBSD 0.9c) that "high" values of maxusers caused
hp300s to behave strangely, i.e. processes would just wedge. It was a
real problem at times, especially if getty had to re-spawn on the console
so root could log in to reboot! I believe Jason Downs or myself even
filed a PR about it. It was the worst on an hp380 which was eventually
to become ftp.cs.orst.edu.
I'm going to give this a crack on my hp300s, and maybe even close a PR or
two :-)
Thanks Chuck and Nik.
