Yes, it would be useful (I mean CPU/MEM/#PROCS limits), but as I understand
there are two kinds of opinions about jails. First is that it should be
extended and allow to create a real virtual server and second is that it
should be light-weight.

Could you describe the brokeness? I've made some fixes a week or something
ago, I just created a patch against HEAD if you want to try it:
http://people.freebsd.org/~pjd/patches/jail_2005020101.patch
There can still be some remaining issues, but I don't have time for more
detailed tests.
The thing that can be useful IMHO is possibility to use
reboot(8)/shutdown(8), etc. inside a jail, but...
I'm unfortunately too busy with other (probably less interesting, but
profitable) projects.
