I always thought that the main arguments for green threads was their cheaper context switch compared to native threads and their less usage of memory.

The next point might be if it's harder to get the same performance characteristics with native threads on different platforms.

Yeah, outside of Linux threads are dog slow. But Linux's implementation demonstrates that they don't have to be, and if you have serious scalability problems you're going to know your architecture well in advance.
