Compatibility with redis-py lock implementation

[philipp-schmidt]

On first glance the implementation here seems to be the same as the lock implementation of redis-py, a very common python redis client implementation.
As debugging (and especially reproducing) lock errors can be very hard though, could someone with more insight (maybe @danielstjules?) confirm that this implementation is compatible with the way redis-py implements its locks?

The Lua Scripts in both implementations basically do the same and the lock acquiring is the very same call.
