yeah. i'll fix the manual. thanks for noticing. > Bummer. > > What I guess we (VM tricksters) would really want is MAP_NORESERVE... that's not very hard to add. uvm has a concept of maxprot, which is the maximum protections one can add to a page. userland doesn't really get any control over this however. there could be a flag that leaves maxprot as none, and then we wouldn't need to count that as memory.
