Thanks for contributing!

Could you please explain the motivation for this change? Will it help to reduce the binary size, will it make the builds faster?

I think this is a useful feature, PR would be more than welcomed!

@patramsey would you be interested in creating a pull request with the feature you described? I'd be happy to review and merge it. Thanks!

`f.mu` is `sync.Mutex` which is a local Mutex not a distributed one (which requires additional services like etcd, redis, etc).

Hm... good point. I think you're right and the Mutex in the `FixedWindowInMemory` does not seem necessary. Could you check if it can be safely removed?

@andresvia would you be interested in creating a pull request with this change?

Unfortunately this issue is still relevant. `brew uninstall gpg` resolved it for me, although that means i can't use gpg anymore :) Any suggestions on how to make it work?...

Deleting `/usr/local/Cellar/protobuf` directory resolved a similar issue for me.
