some ut failed

Hi,

Some ut cases failed, such as:
def test_decorator(self)

The test redis_cache.test_rediscache.test_flush_namespaceis failing as well.

The keys are removed if we search on Redis using the keys but still present when we use SMEMBERS.

This is the test error trace:

Traceback (most recent call last):
  File ".../redis-simple-cache/redis_cache/test_rediscache.py", line 207, in test_flush_namespace
    self.assertEqual((len_keys_before - len_keys_after), 2)
AssertionError: 0 != 2
