So I have worked up some thing usable fore us based on the 7.0 code from 
the wiki.

This patch is for 7.1 in implements both soft and hard memory limits.

Details are here:
http://www.tomjudge.com/index.php/FreeBSD/Jails/MemoryLimits

Changes that add supporting infrastructure for cpu limiting are in the 
patch but changes to the schedulers have not been included.  If you need 
the scheduling support you will need to patch sched_4bsd with the code 
from the original patch set here:

Hope this is useful for some people.
