You could do it this way, but using "send .. in" would make a lot more
sense. Note that "send .. in" messages are also only sent when there
aren't any OS-generated events in the queue, which means that
interactivity always has priority over these background tasks. You do
still have to exit from your "continueIndexingALittleMore" handler
after a short time (say, 200ms) periodically, though.
