It should only take a few seconds to write such rules for simple views --
see the examples in the Programmer documentation.

I suppose it won't help here to suggest using memory mapped I/O, because
someone will complain their platform doesn't support it. I wonder though if
there could be an optional patch to use mmap for all disk I/O, not just
shared memory!
