When there is no idle workerthread available, an incoming requests will
get queued until a thread becomes available.

We called this "overflow" because it overflowed the worker thread pool.

However, "overflow" gives the impression that the request is somehow
lost, which it is not.

"queued" gives a much more precise idea what goes on.
