User supplied Queues and Executors #9
Description
Desire to allow user to supply their own queue to Bukkit/Sponge implementations.
Major Issue:
Right now, a factory is expected to be 1 to 1 relation to its queue.
if factory shuts down, the queue shuts down.
But what if 2 factories share the same queue?
How do we process shutdown of a factory and block until its tasks are flushed from the async queue but allow the other factories to continue?
