    Fixing this has been discussed internally, I imagine, by many of the
    affected OS's.  The problem is a resource stavation issue - in this
    case mbuf's.  Arguably, it shouldn't "lock up", just freeze up anything
    that does networking.
    
    I imagine you could lock up more than just the *BSD's with this program.
