> The Broker installs connection tickers to guard against a new connection that sends no bytes or sends bytes too slowly.  If the ticker expires, the connection is closed with a {{CON-1003 : Closed due to inactivity}} message.
> However, currently a side effect of the Selector Thread's algorithm will mean that a connection that whilst ready for read but cannot be scheduled on an IO Pool sufficiently quickly enough will also be closed.  This is unfair.
> This problem will mean that establishing connections to a busy broker may be unreliable.  Also a retry effect on the client may exacerbate the situation.
