You might have more joy if you allocated one HUGE chunk immediately on
startup to use for the pack, and then kept re-using that chunk.
Well, it is not _one_ chunk. The windows/cygwin abomin...combination
may take an issue with this: it seem to copy complete address space
at fork, which even for such a small packs I have here takes system
down lightly (yes, I tried it).
Perhaps planned mmapping only parts of packs would help there.
