You are right. There is a bug in my code, because it depends on lovely.memcached, which does not support 'cas' :(. I didn't remember that the code was not tested. Sorry! However, is your implementation thread safe? Maybe I am blind ;). That was the reason I used lovely.memcached as memcached connector. Each thread has its own connection and namespace to store keys. Therefore, the locks from one or more zeo-clients with multiple threads ẃere distinguishable.
