def mc_lock(namespace, on_lock_failed) :
    '''
    This uses memcached to provide a lock on a key before performing some operation.
    The first argument provided to the decorated function will be the key.
    It will be preceded by $namespace to ensure uniqueness
    on_lock_failed is a function that will be called if we fail to acquire the lock
