 // SignalThread - Base class for worker threads.  The main thread should call
 //  Start() to begin work, and then follow one of these models:
 //   Normal: Wait for SignalWorkDone, and then call Release to destroy.
 //   Cancellation: Call Release(true), to abort the worker thread.
 //   Fire-and-forget: Call Release(false), which allows the thread to run to
 //    completion, and then self-destruct without further notification.
