> As per discussion on GIRAPH-357, in standard application chances that we get
> to use client-side combiner are very low. I experimented with benefits which
> we can get from not having the client-side combiner at all. It turns out that
> having a lot of maps in SendMessageCache, and then collection inside each of
> them, really hurts the performance.
