Tom,
Thanks for your clarification.

I agree.

I agree that it is hard to say which part should be first C++-ified,
or C++-ified easily.  When the first step (python reference counting
and exception) is done, we may have a clear view of which part should
be C++-ified.

That is good to me.

Right, that is the reason I ask do we plan to move GDBServer to C++.
This makes sense to me.
