> More useful would be what the Gnome Terminal do.

or telnet session), it warns you (on close) that there is something
active.
Not sure whether that's always what one would want, but I guess it's
probably the least annoying while protecting programs from being killed by
accident.
> I thought waitpid() could be used to check that, but I probably misread
the documentation.
You might be interested in

tcgetpgrp()]. If the terminal's foreground group is not the shell, then
something else is actively running. That doesn't catch stopped or
background jobs, though. You could test what Gnome Terminal does in these
situations. Well, or look in its source code. It might make use of procfs,
though, which we don't have.
