arguments and return values that cannot be transported through the RPC
barrier, in particular frame and traceback objects.

Request the RPCServer start the Python subprocess debugger and link. Set
up the Idle side of the split debugger by instantiating the IdbProxy,
debugger GUI, and debugger GUIAdapter objects and linking them together.
Register the GUIAdapter with the RPCClient to handle debugger GUI
interaction requests coming from the subprocess debugger via the GUIProxy.
The IdbAdapter will pass execution and environment requests coming from the
Idle debugger GUI to the subprocess debugger via the IdbProxy.

Unregister the GUIAdapter, which will cause a GC on the Idle process
