Yeah. I considered this critique, which is why I added the performance caveat. The thing is, libraries of other languages are being written abstractly over the native eventing systems on the OSes. For example, the MIO library in Rust, is an abstraction over epoll, kqueue, and the MS primative. Not one over the POSIX standard. This means that if you use that in a Rust library, you get that platform independence for free.
