Here is an actual dump of what happens:
neal@hurd:~/test $ settrans -ac tt trivial_translator
neal@hurd:~/test $ echo "foo" > tt
neal@hurd:~/test $ settrans -g tt
neal@hurd:~ $ kill 52
No contorl c, no control z.
I had an extra terminal open this time and was able to
kill the login shells and then:
neal@hurd:~ $ kill -9 52

GDB does not resond to either a return, a `q', a control c or
control z; It must be killed from another shell.

No offense taken. Not only do I assume that I don't know, I know
that I have no clue ;).
I hope this was a bit clearer.
