Otto is not safe to use for concurrent access, consider using multiple instances it that works for your use case.

If you need safe concurrent access, we'd be willing to consider a PR if it doesn't negatively impact the single access use case which is the common use for Otto.

Thank you, I think you need to consider this PR
