Make the 'maxusers 0' auto-sizing code slightly more conservative. Change
from 1 megabyte of ram per user to 2 megabytes of ram per user, and
reduce the cap from 512 to 384. 512 leaves around 240 MB of KVM available
while 384 leaves 270 MB of KVM available. Available KVM is important
in order to deal with zalloc and kernel malloc area growth.
