Three general possibilities:
(1) aControllerObject is nil.
(2) The main run loop is not running for some reason.
(3) The main run loop is not running in one of NSRunLoopCommonModes.
Assuming you've eliminated (1), I'd look at (3).

Does anyone know of any issue that would cause
performSelectorOnMainThread to not actually perform the selector but
not report any kind of error? I use threads very often and have
never had a problem like this, but when I call:
[aControllerObject
performSelectorOnMainThread:@selector(doSomething:)
withObject:anObject waitUntilDone:NO];
absolutely NOTHING happens. No log messages, doesn't pause on break
points, and certainly no exceptions. But if I do this:
[aControllerObject performSelector:@selector(doSomething:)
withObject:anObject];
it works every time. I'm completely baffled. Has anyone seen
anything like this before?
Thanks,
Ben
