>>OK for me. Maybe we van add an (storage) option to enable/disable locking
any idea for option name ?
lock: 1|0 ?
objectmap: 1|0 ?
-note that both are 2 differents options, but objectmap need exclusive lock enable to get it working.
I'm not sure we need an explicit lock option, maybe objectmap option is enough. (with implicit locking)
I also need to check how it's work with templates and linked clone.
(parent: lock off linked clone : lock on ???? )
