* Next, there is only 1 connector. The ServerConnector.

// and a RejectedExecutionPolicy of CallerRuns.
// Unfortunately, CallerRuns causes lockups in Jetty NIO (ticket #1395)
// In addition, no flavor of TPE gives us what QTP does:
// - TPE direct handoff (which we were using) never queues.
// This doesn't provide any burst management when maxThreads is reached.
// CallerRuns was an attempt to work around that.
// - TPE unbounded queue does not adjust the number of threads.
// This doesn't provide automatic resource management.
// - TPE bounded queue does not add threads until the queue is full.
// This doesn't provide good responsiveness to even small bursts.
// QTP adds threads as soon as the queue is non-empty.
// QTP as of Jetty 7 uses concurrent.
// QTP unbounded queue is the default in Jetty.
// So switch back to QTP with a bounded queue.
