	* Filters: don't apply refcounts on composition, do it only
	(and always) in the builder
	* Count pending timeouts, and export them

	fails.  This fixes a connection leak

	messages to timeouts in finagle (so beginners know which
	settings in the client and server builder caused them), I'm
	adding lots of human-readable messages to the various
	TimeoutExceptions.
	* some timer bug fixes, particularly: TimerToNettyTimer:
	actually cancel underlying task.

	watermark.
	* quench exception for setting multiple Promise values when

	creates the client side annotations, no support for passing
	along ids and such to the memcached server.

	* support end-to-end cancellation in finagle clients; fixes
	possible pool starvation conditions, and allows clients to
	cancel requests and reclaim resources

	.timeout.  .connectTimeout is the end-to-end connection
	timeout (includes acquisition & TCP time), .timeout is an

	* misc. bug fixes
