would you care to give references to this being done in plan 9 or similar operating system? i would hope the discussion is much bigger than the resulting code. this discussion has boiled down the issues for me. this is what i remember plan 9 overcommits memory three ways 1. when a process forks, the cow pages are counted once. 2. plan 9 hands out brk'ed pages it doesn't have. 3. the stack is potentially very large (16mb), grown implictly and not reserved. by the way, what are the scare quote quotes for? participants might take that in the wrong way. - erik
