Bug Description
Creating a volume from another volume (clone) or from snapshot, is serialized due to lock.
A user wants to create multiple volumes from the same volume/snapshot. Unfortunately this happens in serial because there is a lock in the volume manager to prevent the source volume/snapshot from being deleted, while the creating is ongoing. This prevents more than 1 create from happening at the same time.

I don't believe we should be using a shared lock between create and delete to prevent a delete taking place on the source.
