Comment (by jdemeyer):
Replying to [comment:7 pbruin]:
> The fact that `sage-CSI` is run does mean that if GDB is available, it
now takes about 10 seconds before you are back at the shell. Pressing
`^\` a second time does not immediately interrupt `sage-CSI`. I'm not
sure why; is the `^\` somehow intercepted by GDB? Pressing `^C` during
these 10 seconds does generate a Python `KeyboardInterrupt` in `sage-CSI`,
but does not immediately get you back to the shell either.
That's right indeed. It seems that, once GDB gets hold of a process, there
is no easy way to get out.
