VMS called theirs a "Working Set Quota" (WSQUOTA). I believe that FreeBSD has a similar quota systems to avoid a simgle process trashing the cache (like what happens when you run the linker in UnixWare). Actually, I'd like to see a paper on the new VM system; I've been considering Dynix-like per processer page caches and other issues of concurrency. It'd be nice to know the intended overall design (plus such a paper would probably have historical significance 8-)).
