Exactly why I mentioned it.. along with shared pid space.. Both would be
relitavly low cost to maintain within the kernel, but I'm sure the
developers have a helluva time keeping up.
Once these basics are in, its alot less work for people trying to do more
advanced cluster stuff..

I've played with it a bit (earley releases) and I've found it to work
rather well (well, a bit slow when I used it.. But hey it was alpha)..
This really should be included..
