    Also for some reason this patch also seems to fix the seg-fault
    issues I've been having on x86-64 for ages and ages (where a buildworld
    would occasionally seg-fault).  My /usr/src has always been mounted NFS
    on my test boxes, but I never expected it could be the cause of the
    seg-fault bug.  So far my buildworld loop has run 84+ iterations with
    no faults.
