PROPOSAL: Use python async module

[merqurio]

Using new python async module could be beneficial in a case like slackbot.

The MessageDispatcher.loop could be an @asyncio.coroutine and the main Bot.run simply a loop.run_until_complete.

Understanding that concurrency is about dealing with lots of things at same time and parallelism about doing lots of things at once, I think async coroutines are a good choice in this case.

Pros:

• Non-blocking
  • Various Bots working in parallel
  • DB transaction
  • Cross-services checks (Long HTTP waits)
• Add routines that wait (#21)

Cons:

• Python 3.4+ only
• Rewriting code

I would love to hear your opinions on this.

@merqurio Why did you closed this? I totally agree, but...

To avoid Python 3.4+ only disadvantage, it could be done using Twisted (event-driven).

Sorry, We don't use slack any more. Bests
