Once in a while, we get a ticket about failures when running the Django test suite on PyPy. Sometimes they are bugs in PyPy, other times we use something that's not available or behaves differently in PyPy. Is it worth adding PyPy to our continuous integration so we can proactively address these issues?
(We can't test with pypy3 since that's based on Python 3.2 which we've dropped support for in Django 1.9.)
