Comment 3 for bug 1932203

I drove this one around the block a couple of times, and it works for me on 3.7.3, 3.9.0, and latest master.

I've pushed the patch to master, rel_3_9, rel_3_8, and rel_3_7. I figure this is a performance patch that is close enough to a security patch to warrant being in a 3.7.4 relase.

Thanks, Jeff!
