Oops. I am sorry for giving such a misleading backtrace. Of course, to
produce the backtrace I had to suspend gdb, so it got backgrounded and then
I could run gdb with the batch option on the suspended gdb to see where it
is hanging. So what you saw was simply the suspended gdb.
I have now set up a neighbourhurd (our new name for subhurd ;) and can do
proper debugging. But now it is hanging in poll. And I have tried the
latest term in stdio environment, which works, too.
Thanks,
Marcus
