Isn’t that just a bridge to an existing OS level feature? Also is GCD green? (As in light weight, co-operative muti-threading)

Yes. A feature well designed for this very purpose.

GCD tasks are not green threads but they're not direct threads either (even though they're used under the hood). They're more lightweight and much faster to create (than direct OS threads).
