//
// Base class that implements thread functionality. Subclass this class and
// implement the virtual ThreadEntry function. When you instantiate this
// class a thread gets created which will call ThreadEntry and when that
// function exits will call ThreadExit. These objects should be created using
// operator new because the default implementation of ThreadExit does
// "->Release()". You should override this function if you don't want this
// behavior. The threads are also created SUSPENDED. You make any changes
// that are required in the subclass' constructor. At the end of the
// constructor or from the caller of operator new a "->Resume()" can be
// invoked to start the thread.
