Classes
class	Threads::Atomic< T >
class	Threads::AtomicPointer< T >
	Atomic instantiated with a pointer. The class really only handles the casting from a void* to a T*. More...
class	Threads::SpinLock
	Is an alternative to Mutex. It is a lock which causes a thread trying to acquire it to simply wait in a loop ("spin") while repeatedly checking if the lock is available. Because they avoid overhead from operating system process re-scheduling or context switching, spinlocks are efficient if threads are only likely to be blocked for a short period. More...

Namespaces
	Threads
	interface to threads that should be portable.
