Ok, we have those choices:

1. Make -exec-continue work on all threads, until -thread-select is used.
2. Make -exec-continue work on one thread, and add another command
to operate on all threads.
3. Make -exec-continue still operate on all threads, unless
and explicit option to make it operate on a thread is given.

You've indicated that (1) and (3) are about the same in complexity for you --
am I right? I personally prefer (3), since it does not implicitly changes
the meaning of existing commands.

Surely, non-stop mode does require some changes in frontend, but the
fewer changes are, the better, IMO.
