We've done some initial tests with your O(1) scheduler. We were 
measuring the latency impact of N idle connections on 1 active 
connection (N=0,9,99,999). See the attached graph.

The test was run via loopback interface. The idle connections were 
attached to a queue separate from the one that the active connection was 
bound to. Note that the tests were performed on a high-end box (8 cores, 
a 3GHz) - the difference will be greater on a slower box.

Tomorrow we'll proceed with both active and idle connections bound to 
the same queue.
