    If you don't have the disk necessary for a standard overcommit model to
    work, you definitely do not have the disk necessary for a non-overcommit 
    model to work.

    If you were to try to implement overcommit protection on a system
    with insufficient disk space, it probably wouldn't have enough reservable
    space to run basic system daemons, much less any actual servers.

    Read the part again where I mentioned the swap requirements for a 
    non-overcommit model to operate at the same level as the current model.
