So to use GCD I have to rip apart all of my code that uses threads/runloops at once and rewrite it? (As I’ve said, I don’t mind upgrading it bit by bit as I go; it’s the big-bang approach that scares me.)

I keep explaining this. So code that uses GCD APIs can coexist with code that uses runloops.
(Even Apple hasn’t finished doing the conversion. Note that you cannot use NSStream with GCD because its callbacks can only be scheduled on runloops, not on queues. There are likely other APIs like this that I just haven’t run into.)
