If you're collecting them, I found another bug, although it might not
matter to most: if I put my laptop in S3 sleep during a send/receive, it
reliably breaks the copy (this is disk to disk, not disk to network).

Not a problem for a server, but on a laptop, if you happen to have a
background backup from disk1 to disk2 and you put the laptop to sleep,
it will break the backup in a way that's not recoverable and you need to
start back up from scratch.

btrfs send | btrfs receive gives:
Create a readonly snapshot of 'home' in './home_ro.20140216_21:03:53'
At subvol home_ro.20140216_21:03:53
At subvol home_ro.20140216_21:03:53

ERROR: crc32 mismatch in command.
Error line 137 with status 234

If that helps, I can reproduce at will.

Thanks,
Marc
