+# XXX KBK 25Jun02 The handlerclass is expected to provide register/unregister
+#                 methods.  In Idle, RPCServer is instantiated with
+#                 handlerclass MyHandler, which in turn inherits the
+#                 register/unregister methods from the mix-in class SocketIO.
+#                 It is true that this is asymmetric with the RPCClient's use
+#                 of register/unregister, but I guess that's how a SocketServer
+#                 is supposed to work.
+
+#                 Exactly how this gets set up is convoluted.  When the
+#                 TCPServer is instantiated, it creates an instance of
+#                 run.MyHandler and calls its handle() method.  handle()
+#                 instantiates a run.Executive, passing it a reference to the
+#                 MyHandler object.  That reference is saved as an attribute of
+#                 the Executive instance.  The Executive methods have access to
+#                 the reference and can pass it on to entities that they
+#                 command (e.g. RemoteDebugger.Debugger.start_debugger()).  The
+#                 latter, in turn, can call MyHandler(SocketIO)
+#                 register/unregister methods via the reference to register and
+#                 unregister themselves.  Whew.
