Hi

As said earlier, it's on PyPi: https://pypi.org/project/eventfd/

However, it's only at version 0.2 and hasn't been changed since 2016. Digging a bit deeper, there's an unresolved issue that suggests more work is required.

Issue: Race condition in "set" can lead to a bad state
https://github.com/palaviv/eventfd/issues/2

Perhaps a good first step would be a code review of palaviv's enventfd, and finding a fix for this issue.
