paul lalonde's request is a good one, but i think a useful qualification
is that it should also be shown in practice to have a reasonable implementation
on several agreeably different architectures.  one of the reasons mmap is
bad is that like job control it whacked some vague ideas into an existing
system without reference to its existing conventions, then vaguely extended
it in a vague way from time to time, vaguely different from platform to platform,
and with vague documentation.  ``could they be any more vague?''
