It's possible that there is another problem. However, David's latest
logs (posted in bug 690) show this:

- read from worker socket thread blocked on allocation of buffers
- worker blocked in send() (thus unable to recv()).
- service blocked in send() to worker

Part of this should be addressed by the NIO stuff, so we'll need new
logs.
