Do you manage to just import gevent without logbook? Do you still get these warnings

Known issue with gevent: https://github.com/gevent/gevent/issues/1260

The issue describes a workaround until the next gevent release

Ok. Closing this one as this is not an issue with Logbook.

Thanks for reporting!
