Comment (by vbraun):
I took some time to understand the gap pexpect interface. Altogether, I
think it would be better to base it on the normal interface which seems to
be more stable and definitely has more exposure. But we are using the
package mode (`gap -p`) and that is neither documented (apart from the
source) nor does it behave particularly well when you send Ctrl-C. But
that is definitely for another ticket.
I did add more checks after `interrupt()` that the pexpect interface is in
a sane state, and restart gap if it is not. I ran 500+ iterations of the
doctest and do not get any failures anymore. I'm pretty confident that
this is at least as good as we had before, so please review.
