If you're worried that Apple may someday special-case a delay of 0, you could always specify a delay of 1e-37 or so. Although the documentation for performSelector:withObject:afterDelay: could easily be read to guarantee that the selector will always be scheduled for the next run loop iteration.

If you're worried that Apple may someday special-case delays less than some arbitrary lower bound, you could always try using NSRunLoop's performSelector:target:argument:order:modes: which the documentation specifically states will schedule execution for the next iteration of the run loop.
