Hi Adam,

I have a patch against 7.1 here: 
http://svn.tomjudge.com/freebsd/patches/jail-resource-limits/jail-limits.patch

I will try to bring the patch up to current when I get a chance but I 
have no real need to do this as we use 7.1 in production.

Notes:

    * CPU limiting is not support is not supported unless you use 
shecd_4bsd.
    * I have not tested this on any system yet, just compile tested, I 
am putting it though its paces right now.

Tom
