That's my gut feeling, too. I'd have a slight worry that the OS's paging
behavior may respond differently if we have more memory mapped. But
that's not based on numbers, just a fear of the unknown. :)

If we have infinite windows anyway, I suspect we could just mmap entire
packfiles and forget about all the window complexity in the first place.
Although IIRC some operating systems take a long time to set up large
mmaps, and we may only need a small part of a large pack.

Thanks. Let us know if you get any results, either way.
