Thanks for the explanations!

So instead of or in addition to the warning, can we skip this test in
case of no controlling terminal? Because the situation where it
currently shows up reproducibly (on the build daemons), it's always
without controlling terminal.

(The one case where it seems to hang for me with a controlling
terminal, I wonder if I was just not patient enough. I think I waited
for at least 20 to 30 seconds before pressing Ctrl-C, but I'm no more

Well, it at least hangs under some yet to be determined conditions. So
skipping the test if it doesn't do anything useful seems a step
forward for me. :-)
