Locker

locker provides a mechanism for creating finer-grained locking to help free up more global locks to handle other tasks.

The implementation looks close to a sync.Mutex, however, the user must provide a reference to use to refer to the underlying lock when locking and unlocking, and unlock may generate an error.

If a lock with a given name does not exist when Lock is called, one is created. Lock references are automatically cleaned up on Unlock if nothing else is waiting for the lock.
