> Blocking on the epoll thread is awful. The new rpc scheduler can have lots of
> different queues. Those queues have different capacity limits. Currently the
> dispatch method can block trying to add the the blocking queue in any of the
> schedulers.
> This causes readers to block, tcp acks are delayed, and everything slows down.
