description:
Add a delay between startup of pinger and pingee here too.

XXX: there's apparently some race condition which appears to trigger
if a broadcast arp arrives around the same time as the arpwhohas
is sent.  This causes original packet to never be sent by the
arpwhohas requestor.  If this rings a bell to someone, please let
me know.
