    I don't see any way of using process groups that would allow
    this to work:

    $ make-audio-samples | tee foo | bplay
    ^C

    (bplay is 2-threaded for buffering reasons, IIRC)

    and which would also let 'bplay' use Posix threads and
    their associated signal semantics. A new clone flag
    defining 'signal groups' has the advantage that it lets the
    process decide what signal semantics will be applied to it.
