So I finally got some time to play with this, and I am entirely unable
to reproduce these errors with virtual loop disks. I'm going to chalk
these errors up to transient SATA nastiness, since that's happened on
this system before. Either way, there was no data loss during this
entire operation, so besides a few extra unplanned reboots, things went
extremely well. Excellent work on btrfs, devs, and thanks to everyone
who chimed in to help me.
