	 See Frank Schilder's post about a meltdown which he believes could have
	 been caused by beacon/hearbeat being drowned out by other recovery/IO
	 trafic, not at the network level, but at the processing level on the OSDs.

	 If indeed there are cases where the OSDs are too busy to send (or process)
	 heartbeat/beacon messaging, it wouldn't help to have a separate network ?

	 Cheers,
