Description

Right now we only support 127 concurrent requests against a given native transport connection. This causes us to waste file handles opening multiple connections, increases driver complexity and dilutes writes across multiple connections so that batching cannot easily be performed.

I propose raising this limit substantially, to somewhere in the region of 16-64K, and that this is a good time to do it since we're already bumping the protocol version.
