There is magic sauce in CFRunLoop that runs the main queue as part of processing the runloop. All other queues are managed by code running on a thread managed by libdispatch. The main queue is a special case; it doesn't make sense for this relationship to exist for other queues. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
