You’re right. I think I was implicitly imagining it would be like [NSRunLoop currentRunLoop] in that it would create one the first time it was asked.

I have a vague memory of trying this some time ago and running into trouble; but of course I don’t remember exactly what went wrong.
But in light of Mike’s explanation of target queues and “it’s dispatch queues all the way down”, I can see why getting the current queue isn’t a good approach. :/
