Uh, from what i've read, what I'm seeing is more a consensus that this
doesn't make sense and its not what we want.

The fundamental reason is that the `flexibility' you want acually has
negative utility in many environments.

VM/CMS used a very similar policy for each VM's `virtual memory' on
their godforsaken minidisks: VMs `paged' to unallocated filespace on
their minidisk.  I cant recall that it being anything but an unmitigated pain.
