Use ``attentive`` if you need to wire up a some worker threads that needs to cleanly
shut themselves down on a SIG_INT or SIG_TERM.

``StoppableThread`` is a context managed thread that lives on while in context. Once it exists
context it sets its internal stopped flag that are periodically checked for state. This signals
thread state allowing the thread to cleanly exit.

External state is controlled by a signal event, exiting the main context loop.

Internally use the StoppableThread.sleep() method that is interrupted when stop()ed during
sleep.
