When metadata locking is enabled that means the security commit processing will be run in a fork similar to how namespaces use fork()'s for processing. This is done to ensure libvirt can properly and synchronously modify the metadata to store the original owner data. Since fork()'s (e.g. virFork) have been seen as a performance bottleneck being able to disable them allows the admin to choose whether the performance 'hit' is worth the extra 'security' of being able to remember the original owner of a lock.
