If all you need is fire and forget (i.e. you don't need to wait for the message to complete) then you can do this by simply creating a timer and adding it to the runloop. Don't forget to call CFRunLoopWakeUp after you do this. CFRunLoop is thread safe, which lets you do neat things like this. (Don't let toll-free bridging confuse you: CFRunLoop is *not* toll-free bridged to NSRunLoop, and NSRunLoop is *not* thread safe.)
