To start with, I'd take the naive approach and see whether it worked
well enough for the job. I'd use thread.sleep(), and make sure I had
enough worker threads (configured in server/conf.xml) to handle the

Looks like the Connector's compression facility is checking for an upper

Does anyone know of a way to disable this upper bound?
