    Ah, nice.  I was about to say that we can get rid of PHOLD/PRELE,	
    but actually we can't.  Its original function was to prevent the
    process UAREA from getting swapped.  In DragonFly the UAREA is
    no longer swapped but PHOLD/PRELE serves another important
    function and that is to prevent a process from exiting while other
    bits of the kernel (like [lin]procfs) are accessing it.
