    One other warning, Chuck.  When playing with new system calls, since
    you have to run buildworld to integrate the call into libc, it is
    possible for libc to get out of whack while you are playing with it.

    I strongly recommend making a backup of /usr/lib/libc.so.6 so you can
    restore the original if you accidently blow it up.
