| /* |
| Package 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. |
