> This is actually slightly worse than just using a new thread per broker connection as
it also uses a new Poller for every Connection and the Poller is fairly hefty and includes
a number of fds for its own use. This multiplies the client fd use for clients with many Connections.
> It's not really acceptable that opening 1000 connections should create 1000 threads.
> It should be noted that this isn't the only aspect of the client library that uses excessive
numbers of threads, lets knock them off one by one
