Released 2014-05-07
* :meth:`~nameko.containers.ServiceContainer.spawn_worker` now throws
:class:`~nameko.exceptions.ContainerBeingKilled` if a ``kill`` is
in progress, since some providers may already be dead. Providers should catch
this and e.g. requeue rpc messages. There is a race condition between
completing the kill sequence and remaining entrypoints firing.
