    You are assuming that turning on vmiodirenable is detrimental on a
    low-memory machine.  I don't think it is, because on a low memory
    machine you aren't going to be able to cache very much anyway.  But if
    anyone thinks it is please be my guest and test it on a low-memory 
    machine on verses off.
