Comment 31 for bug 444563

I'm seeing similar problems in a similar situation. I'm not doing backups but I am creating and removing a sequence of lv's and snapshots. Mine are on amd64 karmic. I don't believe I've seen these on lucid with the same code, (which only proves I haven't done enough testing :).

If this is a harmless race condition, it would be nice to have that validated and documented.
