* An object that creates new threads on demand. Using thread factories
* removes hardwiring of calls to {@link Thread#Thread(Runnable) new Thread},
* enabling applications to use special thread subclasses, priorities, etc.
*
*
* The simplest implementation of this interface is just:
*
* class SimpleThreadFactory implements ThreadFactory {
* public Thread newThread(Runnable r) {
* return new Thread(r);
* }
* }
*
*
* The {@link Executors#defaultThreadFactory} method provides a more
* useful simple implementation, that sets the created thread context
* to known values before returning it.
