I've got myself confused again. Could someone confirm or deny how
unification affects memory usage.

I was under the impression that if a unified (hard linked) "program" was
started by one guest the code for it went into the text area of memory
and any needed data area was allocated from the heap. Then when another
guest started the same program kernel-magic happened and basically the
same code was used but a new chunk of heap was allocated/used for its data.

I'd like to make a simplified drawing of how the Linux-Vserver way with
unification saves memory. Have I got it all wrong?
