# Hitting Memcached while running tests is a _really_ bad idea. This class is basically a glorified hash, keeping track of what's given to it, 
# seems to work acceptably in test env.
# The way the Cache module works, it assumes a constant named CACHE to keep the actual holder for cached data - this class provides what seems to be needed for the
# engine not to complain
