Just cross-posting this from the PA mailing list. Ross has written another
great article on concurrency, lock-free algorithms, message passing and
more.
You'll find more than a few of these patterns manifested in Mixxx. I think
it would be useful if we spent some time creating some building blocks
based on these patterns. Every instance of these within Mixxx is currently
a one-off except for our ring-buffer (which we store from PortAudio anyway
;).

Subject: [Portaudio] Programming with lightweight asynchronous messages:
some basic patterns
To: Portaudio Mailing List <portau...@music.columbia.edu>
Hi Everyone,
The subject of using message queues to communicate with the PortAudio
callback comes up here from time to time.
I just wrote a new blog post trying to capture some of the high level
mechansisms that might be used in this scenario [warning: it's not short,
but it has pictures :) ]

lightweight-asynchronous-**messages-some-basic-patterns<http://www.rossbencina.com/code/programming-with-lightweight-asynchronous-messages-some-basic-patterns>
It's rather general and abstract but I hope it helps someone.
I'd love to hear some feedback if anyone has any thoughts about this
material.
Thanks,
Ross
