> The current behavior is to clean up any messages and state for a runnable instance during its start up.  This is to make sure things are clean if the instance is being restarted.  
> However, this can result in lost messages to new runnable instance if a message is sent after the container has been assigned to a new instance, but before the cleanup part of the code runs.  Moving the cleanup to the application master when it is launching the container would fix this problem.
