mac os x 10.12

So, I've actually already fixed that particular problem with coroutine on MacOS. However, it still doesn't really work, because ucontext (which coroutine relies on) isn't supported on MacOS.

Fixing this isn't trivial - I need to work out a different way of doing coroutines that works for MacOS. Since I don't have access to a MacOS machine, and know very little about MacOS that's not particularly feasible. Patches welcome.

I would like to fix the build/test scripts so that modules not supported on that platform won't break the whole build. I just haven't had time to work it out though.
