> Currently the selector thread always reschedules the selection task on the workQueue.  In the case where the select was awoken for the purpose of reregistering a connection on the selector, there will be no connection work to be done, so the potential hand off to of the selection task will be needless.
> We can simply optimise the algorithm to hand off responsibility for the selection iff there is connection work that can be consumed by this thread.
