There has been a lot of talk about using file backing instead of swap backing. The typically proposed scenario is for each process to open "$HOME/.backingstore/$$" or some such. There are a lot of interesting applications, good ideas and nifty tricks enabled by this, but there are also some nasty details, a few security concerns and probably a performance impact. All in all it has not happened yet, and given the size of fish we are currently catching in other areas, I don't see it happening anytime soon. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk_at_FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.Received on Thu Jan 08 2004 - 00:37:59 UTC
