UNIX is perfectly happy with "holey" (sparse) files. All that's needed to satisfy the swapfile weenies is a mechanism to deallocate arbitrary file blocks and return them to the free space. Clearly there are performance advantages to holding onto unreferenced swapfile pages for a while, and there should probably be something besides lowat governing swapfile shrinking (and perhaps a way for a user to force minimize-NOW!). -=EPS=- -- Why "modern" operating systems haven't caught up to what, say, TOPS-20 offered in the 1970s(!) defies rational explanation.
