While here, partly tidy up some of the fork1() On an almost-unrelated tangent... Because proc structures are now stored in type-stable memory (via the zone allocator), other places in the kernel which now reference processes by pid and pfind should be able to keep a reference to the proc instead. (There does need to be a version number which gets incremented when proc structs are recycled, but this should still be cheaper than pfind().) This would benefit network applications written around a poll or select loop, since the simple case of selwakeup() uses pfind() to locate the specific process to wake up. -GAWollman -- Garrett A.
