Subject: Terminate 'nothing' behaviour (and potentially others) by signalling
 using an event rather than polling connection state every 100ms

This kind of polling is very expensive with many bots/polling threads and appears to be the primary cause of bot falloff from the client end at higher loads.
Where inbound packet threads can't run in time due to contention and simulator disconnect timeout occurs.
