lp:~allenap/maas/amp-on-cluster has example code for spinning up a
Twisted event loop in the region web application, via crochet. It also
shows how to expose a remote function via AMP in the cluster, and
there's an example client (usable from the command-line) in the root.

There's one issue:

  $ make syncdb
  $ make services/database/@start

  $ make services/webapp/@run
  Starting event loop in process 25744
  Hello from process 25744
  Starting event loop in process 25758
  Hello from process 25758
  Validating models...

In case you missed it, two event loops are being started.

I'm guessing that this might be related to Django's development server,
which can auto-reload iirc. I'm wondering if there's a way to prevent
the start-up code from being run in both processes?
