public interface LockStrategy
Note that some implementations may actually choose to NOT perform locking, when no lock is necessary (cache not shared). Some other implementations may choose to lock the cache for the download of a whole module (not possible yet), or at the artifact level.
The lock methods should return true when the lock is either actually acquired or not performed by the strategy.
Locking used in the locking strategy must support reentrant lock. Reentrant locking should be performed for the whole strategy.
