Yes, traditionally it seems the OS X port was grown from the BSD port, but have since diverged significantly. In the BSD port maintained out of tree, a lot of the code under the `bsd` directories are essentially split by `#ifdef`'s where the OS X and BSD code are almost entirely separate, and the BSD code is synced with, and more closely resembles the Linux code.

The BSD code was broken in commit d3083ac05453c, and in trying to figure out how to fix it again it seemed easier to split the two implementations than to try to force them to coexist. This way the platforms would have less risk of breaking each others implementations.

I can rename it to darwin instead, if you feel that is better. It seemed like "macosx" was more established when I looked around the source tree, but I'm happy to adapt.
