Sorry if I sound a little upset, but I'm really tired of the FreeBSD vs. Linux war. I think it's pointless and don't make any good to anyone or the OpenSource community.
Jail is in some way like chroot (as other has pointed). It imprision some process placing some restrictions to what the process can do and the idea of this new patch is to run an entire new machine (with his own kernel, process list, etc...) over the same machine.
So just stop trying to start a flame and find a better use for your time, I guess that all the community will be happy on this.
