with mmap once you've read in some of a file and made some
modifications is there anyway to avoid those modifications being
swapped out to the backing store? what would be preferable is in the
event of the system needing more memory, rather than swapping out those
modifications, save them directly to the original file -- is that what
happens now, by default maybe, or is there anyway of doing that?
thanks, ben.
