I agree; it's a noble technique. If process A has data that it wasn't
process B to write to disk, there's the pesky problem of getting the
data over to B first. I've experimented with kludging shared memory
onto the VM's memory management scheme. It works, at least under
light loads. It remains to be seen if we'll actually use it, though.
