While I was away adusca released few releases of mozci.
From the latest release I want to highlight that we're replacing the standard json library for ijson since it solves some memory leak issues we were facing for pulse_actions (bug 1186232).
This was important to fix since our Heroku instance for pulse_actions has an upper limit of 1GB of RAM.
Here are the release notes and the highlights of them:
0.9.0 - Re-factored and cleaned-up part of the modules to help external consumers
