conditions being picked up inconsistently

[ejesse]

Similar to Issue #19, we're running apache with mod_wsgi, Django 1.4 and Gargoyle 0.10.3. The difference with 19 is that we always see the condition in nexus, but on the actual site it's wildly inconsistent or slow to pick up the condition change. Best guess is that it's picking up by thread. If we restart Apache everything looks good. Using the Django development server also always works.

If it's any help/makes any difference, we're using gargoyle.is_active to check the conditions.
