Ok.

That test case fail on OS X, though. Should I open a bug?

It is worth noting that this implementaiton has a few behavioral differences between this implementation and the one implemented in objective-c. Part of this difference is due to features like QoS not being cross platform portable or KVO not yet implementable in Swift. This is very much a work-in-progress; it needs unit tests and and a bit more polish, but hopefully it is good enough to get some work started in some other places.
