This feels like a with-output-to-string kind-of-problem.
i.e. the wrapping of collecting the output to a string belongs at a
higher level.

Scheme example:

(define x (with-output-to-string (lambda () (display "foo"))))

That way one can wrap anything and have all the gdb output collected
without having to modify all the individual gdb.execute calls inside.
Dunno if it's as easy to implement though.
