How about you lock all tables and flush buffers, then do the snapshot, and
release the lock. Now backup then snapshot and remove it. Shouldn't take
more than a few seconds for the lock-snapshot-release part, and you avoid
the problem of inconsistent data in your db.

In other places, I've seen people do master-slave replication and using
mysqldump on the slave (cuz mysqldump locks tables as well)
