This wraps a normal ``threading.Lock`` object and satisfies the same

this you should look at ``multiprocessing.Lock`` or ``locket.lock_file``
but will consistently deserialize into the same lock.
So if we make a lock in one process::
lock = SerializableLock()
And then send it over to another process multiple times::
bytes = pickle.dumps(lock)
a = pickle.loads(bytes)
b = pickle.loads(bytes)
Then the deserialized objects will operate as though they were the same
lock, and collide as appropriate.
This is useful for consistently protecting resources on a per-process
level.
The creation of locks is itself not threadsafe.
