Package sync

Package sync provides basic synchronization primitives such as mutual exclusion locks.
Other than the Once and WaitGroup types, most are intended for use by low-level library routines.
Higher-level synchronization is better done via channels and communication.

Values containing the types defined in this package should not be copied.

Useful Types:

WaitGroup
- (wg *WaitGroup) Add(delta int)
- (wg *WaitGroup) Done()
- (wg *WaitGroup) Wait()

Mutex // Mutual Exclusion
- (m *Mutex) Lock()
- (m *Mutex) Unlock()
