    Indeed, sounds much more like a /dev thing than a /proc thing
    at this point ;-)

    Ummm ... how do we make /proc smaller than 1 file to open per PID?
    It's pretty easy to get it down that far. But it still sucks.

    Well it can't be any worse than the current crap. At least it'd
    stand a chance in hell of scaling a little bit. So I took a very
    quick look ... what syscalls are you reduced to per pid, one ioctl
    and one read?
