 True, however this is essentially the same thing that callers to rt_msg2() 
 do (to they structure they pass) when they build a route event.  Clearing
 the whole message could conceivably fix problems where not all the event/
 message payload data is being being zeroed too (althought this may not be
 likely).
 
 The total length of these messages are quite small, so any the extra cost
 to zero the whole event should be similarly small.
