With one thread per process accepting connections, and cross-process
serialization, requests tended to cluster in a single process in
Ryan's and my testing. Once we switched to the poll-accept model, we
had to add intraprocess mutexes. Then, it seemed that requests
clustered less, but it seemed to vary based on speed of incoming
connections. I have a feeling you'll be trying to eliminate mutexes
completely; I haven't tested the behavior in that situation yet.
