Jail CPU/RAM Limits

[Chris Jones]

Hi, folks --- I did up some stuff to put (soft) limits in place for  
CPU and RAM usage in jails as part of last year's Summer of Code  
project, which was originally coded against 6.x.  Over the past two  
weeks, I've updated it so that it's built against -CURRENT; I've  
tested it, and it seems to work, at least on my devel box.

If you're interested in trying it out, please let me know and I'll  
package it up.

Cheers,

Chris
