I think FreeBSD invented kqueue and from a quick search it looks like OpenBSD and NetBSD also adopted it. We've seen at least one person slightly tweak TigerBeetle to run on FreeBSD already through the darwin code paths.

I'm part of that sample set! Was quite surprised how easy it was to get it up and running on FreeBSD. Benchmarking on tmpfs on both, it even had a ~10% lead on Linux.
(Of course, that's not exactly the intended use case, so don't pay too much attention to that number!)
