Definitely! In particular, since I haven't used multi-threading explicitly myself under Cocoa (just POSIX threads under Unix, and SGI-specific threads, ancient ...)

Oh, I was assuming that *all* threads and processes will get managed by GCD ...
This is probably not the right forum for this question, but why are there different APIs?
Best regards,
