OpenBSD's process limits default to low values. You
need to increase them using ulimit or limit depending
on your shell.

Tomcat 5.0 is in ports. Tomcat 5.5 isn't yet for no other
reason then me slacking. Tomcat 5.5 doesn't strickly
require 1.5. It can be run using 1.4 if you use the
compatiblilty libs provided.
