that's interesting, but why `print' functions work correctly, without
sending any SIGTTOU

I would prefer a python-transparent handling, ie `terminal_ours'
called before giving the hand to the Python callback, to hide GDB's
complexity from the script interface (I guess there won't be so many
situations where this case occurs?).
However if `terminal_ours' is very costly (in comparison to the
breakpoint itself), it might not be very wise ...


Cordially,
