(well tested at BEST): -i option can now take FP values (e.g. -i 0.1),

    extremely useful for networking testing.  Other options secured from
    user-level D.O.S. attacks.  -f, -s now root-only.  -i wait times < 1.0
    root-only.  -c count limited to 100 and defaults to 16 when ping run
    by non-root user.
