+// It contains Pipeline which is the actual media player pipeline, it glues
+// the media player pipeline, data source, audio renderer and renderer.
+// Pipeline would creates multiple threads and access some public methods
+// of this class, so we need to be extra careful about concurrent access of
+// methods and members.
+//
+// Other issues:
+// During tear down of the whole browser or a tab, the DOM tree may not be
+// destructed nicely, and there will be some dangling media threads trying to
+// the main thread, so we need this class to listen to destruction event of the
+// main thread and cleanup the media threads when the even is received. Also
+// at destruction of this class we will need to unhook it from destruction event
+// list of the main thread.
