And before anyone is confused, I'll add that *many* of the points John mentions have been addressed in NetBSD already. Except for the behavior when paging space runs out (which is a subject of debate; several Mach-based systems simply panic, while others algorithmically choose processes to kill), there are no reported instabilities in the NetBSD VM system. Also note that I am not saying, and have never said, that we are not going to continue working on it. There are many other improvements to be made, even outside of clustering. However, we do intend to wait for 4.4Lite for some of it. -- - Charles Hannum NetBSD group Working ports: i386, hp300, amiga, sparc, mac68k, pc532. In progress: pmax, sun3.
