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.
