Summary:                    Qualify intervals >1000ms create needless double
OPTIONS transmissions
Description: 

If "qualify=" is larger than 1000ms, then the re-transmit interval (T1)
should be much higher, either whatever qualify= is set to, or the last
value that was returned from the OPTIONS query.  Otherwise, the one-second
default timer triggers another OPTIONS transmission, which doubles the
amount of traffic to the peer every interval.

Didn't seem to make a difference.  The re-transmits are still happening
every 1000ms.  See tethereal output below - all re-transmits of OPTIONS
seem to be 1000ms, even though qualify= is set to 3000 for this peer.
