Detailed Description

DG_dispatch_client is a virtual base class for clients of DG_dispatch. The main service provided is quit coordination. ready_to_quit() virtual function should return true if client is ready to quit. This will remove the client from the DG_dispatch's list, so a subsequent detach() is unnecessary. Hence ready_to_quit() should set the dispatch member to NULL before returning a non-zero value. As a rule, clients should shut down all of their functions prior to returning. For devices, that means resmgr_detach()

As written, this is probably a bad design, since DG_dispatch::client_add is called with a partially constructed client. In a multi-threaded environment, there is a potential for harm.
