Xtrabackup only holds a read-lock on non-transactional tables - if you are InnoDB-only it
doesn't do any locking at all. Also take a look at the --no-lock option to see if you can
work with that.
AFAIK mysqldump with --single-transaction will still read-lock non-transactional tables
for the duration of the backup. It's possible to turn off read lock for MyISAM backups,
but you'll end up with an inconsistent backup.
