self.crash_store is an instance of ```RabbitMQCrashStorage```.  It has a connection parameter within called ```rabbitmq``` that we save as a instance variable called context.  This is an ambiguity in the use of the term "context".  In some places "context" is used to for the variable containing config information.  Other place, the term "context" is used to denote the connection to the resource.  Here I ought to refactor "context" to "connection" to make the meaning clearer.
