"""Simulate participating in a new experiment on a "new" instance.
This test works by loading memcache with a copy of all gae/bingo
experiments before the doppleganger test exists.
After the doppleganger test has been created once, all future calls to
this function simulate being run on machines that haven't yet cleared
their instance cache and loaded the newly created doppleganger yet. We
do this by replacing the instance cache'd state of BingoCache with the
deep copy that we made before doppleganger was created.
A correctly functioning test will still only create one copy of the
experiment even though multiple clients attempted to create a new
experiment.
