I'm afraid this is not a solution as mmap-substring (as well as mmap->string)
creates a copy of the mmap-ed area. Your solution is then equivalent
to:
(call-with-input-file MY-FILE (lambda (in) (pregexp-match (read-string in))))
The copy is a consequence of the memory representation of strings. It cannot
be avoided.
The only solution would be to change pregexp to accommodate mmap, which should
be a good idea and not that difficult to implement but which is not already
here yet.
Cheers,
