The Page Daemon. OpenBSD's buffer cache is (deliberately) subservient to uvm. Page daemon steals memory from the buffer cache, down to a minimum. Numerous page daemon issues found while attempting to get this right. Fun things: Reduce yourself to about 40 pages of mappable kva. Run on a 16 MB hp300 (yes, we still run on these..) Build X on sparc (SS20, yes, we still run on these) Zaurus.. (It's so cute and japanese..) But Mom - I didn't want to grow up to be a UVM hacker... I just want to..
