 Schedules a stability message to be mcast after a random number of milliseconds (range [1-stability_delay] secs).
 The reason for waiting a random amount of time is that, in the worst case, all members receive a
 STABLE_GOSSIP message from the last outstanding member at the same time and would therefore mcast the
 STABILITY message at the same time too. To avoid this, each member waits random N msecs. If, before N
 elapses, some other member sent the STABILITY message, we just cancel our own message. If, during
 waiting for N msecs to send STABILITY message S1, another STABILITY message S2 is to be sent, we just discard S2.
 @param tmp A copy of the stability digest, so we don't need to copy it again
