our memcached system.
We need to install python-ujson on servers and dev instances before
pushing this to prod.

The previous situation was bad for two reasons:
(1) It had a lot of copies of the code, some of them missing pieces:
UserProfile.objects.get(user__email__iexact=foo)
This was in particular going to be inconvenient since we are dropping

(2) It didn't take advantage of our memcached caching.

when trying to use the time module from inside zephyr.lib.
