Sadly, it isn't. But I called on the developers, lets see what happens.

I saw your post in this regard, quite nice!
It seems a good starting point if I should decide to contribute
to gdb.

Thanks, this is indeed the first thing to do. I will check and see whats
going on between the GUI and gdb, and which commands exactly confuse
the former. I already know that these are few, so with some luck I
can even avoid them.
