    SubjectRe: Flood ping

    Anyone considered the fact that this could be a safety feature there to
    keep outside attackers from eating CPU time ?
    Fact is I prefer it this way, why bother putting in a check for localhost?
    I've seen some interesting spoofs to make it look like the packet came
    from localhost...
