Darn. I was hoping you had some mechanism for tracking that. Have you
seen how quicklists work on Linux? They setup page directories after
they've been freed so the whole things don't need to be cleared when
allocated. I thought you could do something like that with page clearing
instead if you had such a mechanism.
} My mistake. FreeBSD zeroes the whole page as well. I traced through the
} code incorrectly.
Great, I'll take a look. Keep me up-to-date if you can, please.
} I'm running FreeBSD-stable right now, though I may switch to -current if I
} get promising results, to make it easier to merge. (There is a web
} interface to the FreeBSD CVS tree at

} FYI, I'm interest in this for my thesis, which consists of two parts: (1)
} utilizing idle resources (cpu, memory, disk/network I/O, disk/memory space)
} for non-interfering background processing (i.e. run processes/threads using
} *only* idle capacities); and (2) to use that mechanism for speculative
} techniques.
