Yes, but in some cases the loop doesn't run for 10,000. It could run for
5 iterations or 100,000 depending on the # if files to delete.

There's no caveat in the docs on the use of
performSelectorOnMainThread:withObject:waitUntilDone:modes - the docs
make it sound that there are no restrictions on how often or which
selectors can be called.

In my case I only call 2 each time through the loop - one method on the
main thread to update the progress bar, one to update the message.

What if you throttle it back to every X (ten, hundred, thousand, etc) iterations? My speculation would be you're overwhelming your receiver.
