Our QNX pdebug protocol does it by defining different communication 
channels for protocol messages and I/O.  The support isn't rolled into 
the FSF tree yet however and there aren't any clients other than 
Neutrino.  Wow.  How incredibly unhelpful of me. ;-)

I know that Cisco has their support ported to newer versions of gdb but 
I hadn't realized that they once had support in the main tree.  I guess 
they haven't gotten around to putting it back in.

cheers,

Kris
