Very interesting! My #contentsChanged went from around 1723 msec. to 440
msec., so this certainly seems worth it.

I don't know how this compares to Scott's tweak, or if they're compatible,
although, my first guess is that they are. My second guess is back to "I
have no idea!"

Still, very interesting. Thanks to you both!
