I should clarify... Bots only respond to bet requests. That's all
The messages are generated by the poker server notifying other bots
in game and server state.

I see what you are saying but...

I deal in tables. A table holds 10 bots. Only bots at this table get
when another bot takes action. All bots get notified when a bot joins
but that's once per test.
The throttling mechanism is that the tables running on machine A have
to do with tables running on machine B unless bots from both machines
a single table. Even then bots are limited to receiving notifications of
actions taken by bots sitting at the same table.
Does this make my diagnosis correct?
