What happens if all redis nodes aren't available

Hi,

I'm currently using pottery for redlock purposes with 1 redis master.
I'm aware 5 are needed to eliminate a single point of failure but as it happens I'm bound to 1 node.

My question is, what's the expected behaviour should the node fail or be unavailable?
The following will cause my code to hang forever on trying to acquire the lock:

redis = Redis.from_url("redis://wrong_url")
lock = Redlock(key="name", masters={redis})
with lock:
    print("Never prints")
print("Never prints")

I think the appropriate behaviour is to either raise an exception or skip everything covered by the lock?
Just blocking the process isn't good?

Didn't mean to answer my own question but I just noticed the optional parameter raise_on_redis_errors.
Btw I couldn't figure out what context_manager_timeout does.
