AtomicBool gives an atomic boolean variable.

AtomicDuration is a wrapper with a simpler interface around atomic.(Add|Store|Load|CompareAndSwap)Int64 functions.

AtomicInt32 is a wrapper with a simpler interface around atomic.(Add|Store|Load|CompareAndSwap)Int32 functions.

AtomicInt64 is a wrapper with a simpler interface around atomic.(Add|Store|Load|CompareAndSwap)Int64 functions.

AtomicString gives you atomic-style APIs for string, but it's only a convenience wrapper that uses a mutex.

Semaphore is a counting semaphore with the option to specify a timeout.
