Yes, that was my impression as well when I looked at it yesterday. The monotonic_linux() bit that's quoted is platform-specific because it uses CLOCK_BOOTTIME with clock_gettime(), but that seems supported on BSD systems as well. It's probably just that no one tried to run it, and no one spent any effort on it. I can't find a single mention of "BSD" in the issue tracker.
