Shutdown

It is a good practice to call close(cb) on the factories to release all resources once you're done, or at shutdown if you want your shutdowns clean and graceful (the log-lived redis or mongodb connections are terminated here, for example); also, you should loop over your queues and perform a drain() on them before calling close() on their factories: this will ensure any un-consumed data is popped, and any unwritten data is written. Also, it'll ensure all your (local) waiting consumers will end (on 'cancel' error).

note

Factories do not keep track of the created Queues, so this can't be done internally as part of the close(); this may change in the future.
