I find LockOwnership a bit cumbersome. I guess you don't want just
Lock but to include the sense of ownership. Would you consider one of
these...
* Locker "A person or thing that does an action indicated by the
root verb" [1]
* Lockee "Less commonly added to verbs to form words meaning a
person or thing that is the subject of that verb (ie, who or that does
an action), especially where a passive sense of the verb is implied."
[2]
* OwnLock
* OwnedLock
