So Timers Retain Their Targets...

Why do timers retain their targets? It's not documented (as far as I could find) but it's obviously happening.

I have a timer that's created when the text in a field changes and in the dealloc method of the timer's target, I invalidate and release the timer. I thought this would have handled the case where the object closes before the timer fires (logically it would) but since the timer retains the object, dealloc isn't called until after the timer fires which causes a crash.
