The cover letter doesn't acutally have a description of what "memmap on
memory" *is*.  A nice overview to help readers understand what they're
about to look at.  A description of what value this feature brings to
our users.  Use-cases.  That sort of thing.

I guess the [1/N] changelog covers it, but it's hard to tell.  It isn't
exactly broad-sweep overview.

Probably something short would suffice.  There are plenty of examples
on the mailing list, please take a look and send us something?
