It solves several problems. The user no longer has to create a pty to
give to GDB to separate the inferior output and the console output.
(CGDB will have to anyways, since it uses the terminal). Some of the
target's apparently write to STDOUT/STDERR, and that get's confused with
the MI output. Also, thing's like 'shell' and potentially other case's
get mixed in with the MI output. Finally, if we have several
interpreters going at the same time, we could have them all output to
there own descriptor.
