title: Async multiprocessing python
body: <p>So I've read this nice article about asynch threads in python. Tough, the last one have some troubles with the <a href="http://www.dabeaz.com/GIL/" rel="noreferrer">GIL</a> and threads are not as effective as it may seems.</p>
  
  <p>Luckily python incorporates Multiprocessing which are designed to be not affected by this trouble.</p>
  
  <p>I'd like to understand how to implement a multiprocessing queue (with Pipe open for each process) in an async manner so it wouldn't hang a running <a href="http://aiohttp.readthedocs.io/en/stable/" rel="noreferrer">async webserver</a> .</p>
  
  <p>I've read this <a href="https://stackoverflow.com/questions/32955846/in-python-is-there-an-async-equivalent-to-multiprocessing-or-concurrent-futures">topic</a> however I'm not looking for performance but rather boxing out a big calculation that hangs my webserver. Those calculations require pictures so they might have a significant i/o exchange but in my understanding this is something that is pretty well handled by async.</p>
  
  <p>All the calcs are separate from each other so they are not meant to be mixed.</p>
  
  <p>I'm trying to build this in front of a ws handler.</p>
  
  <p>If you hint heresy in this please let me know as well :)</p>
