If N threads are running and busy each further incoming Runnable is queued until one of the threads has finished its current job. If a worker thread becomes idle (no more job in the queue) it is hold alive for 5 seconds. If during this period of time no new Runnable is enqueued the worker thread dies. author:    Sascha L.
