When I run the load test, I get a number of Thread.dumpStack stack
traces with the "lock contention" message. I wonder whether this is OK or
represents a problem. There is no hang or anything, and the client
doesn't complain, so I am guessing it is OK (in which case we may want to
remove the message?).
