----------------------------------------------------------

We could also implement something like RATE_LIMITER for certain events ! E.g. we cannot send more than 5 STABLE events / 10 seconds. If we exceed this, the event in question would simply get discarded...

This functionality could be added into RATE_LIMITER ! By default, we check against Event.MSG, but we could also add other events into the hashmap and check against them in down()...

> max_bytes should be determined as a function of the available memory, a max value that cannot be exceeded and the number of nodes in the cluster.
> If we have more cluster nodes, and everyone sends messages, then *not* changing max_value would lead to too many STABLE messages being sent !
> An example could be: max_bytes="1m" cap="0.25" // 25% of the available heap
> If we have 5 nodes in the cluster, max_bytes would be set to 5m. With a heap of 100MiB, if we have 30 nodes, max_bytes would be set to max(30Mib, 0.25 * 100 Mib) == 25 MiB.
