Comment 1 for bug 938594

I've tested this branch and it fixes the problem we were having too. It wasn't from a XA transaction, but we were getting the same assertion failure.

Also, our prepare times for --redo-only have gone from about 30 minutes to 15 seconds, (doesn't seem to do log recovery at all anymore) not sure if it should've been like this before but the tested backups are still valid so that's pretty good!
