This would be a cool thing. We could squabble over the details, but if
it did what you said above and left some room for tweaking I'll bet
people would be [even more] pleased [though we are already ecstatic now]
with the vserver project. Of course, I'm still using CTX 17, so I'm
pretty easy to please I guess.

I'd be curious to know what happens when there is contention for that
pool of RAM. I've got a nightly batch job that lasts 15 minutes but
uses most of the server's ram during the process. Right now, everything
works OK, but I suspect under this "vserver panacea edition" I would
have problems because idle vservers will be allocated their minimum ram
even though they don't need it.

I guess I could just allocate 4MB of RAM as the minimum or some other
small number to get the effect of what I do now... still, a bit thought
provoking.

Keep up the interesting conversation and work,
