Erik Johnston fca28d243e Change the way we create observers to deferreds so that we don't get spammed by 'unhandled errors' 2015-05-08 16:28:08 +01:00
Erik Johnston 1c82fbd2eb Implement create_observer.
`create_observer` takes a deferred and create a new deferred that
*observers* the original deferred. Any callbacks added to the observing
deferred will *not* affect the origin deferred.
