So, while we're at it, what's the current state of people's thinking
on using mmap rather than shared memory for data file buffers? I
see some pretty powerful advantages to this approach, and I'm not
(yet :-)) convinced that the disadvantages are as bad as people think.
I think I can address most of the concerns in doc/TODO.detail/mmap.

Is this worth pursuing a bit? (I.e., should I spend an hour or two
writing up the advantages and thoughts on how to get around the
problems?) Anybody got objections that aren't in doc/TODO.detail/mmap?
