static void	oasys::atomic_incr (volatile atomic_t *v)
	Atomic increment.
static void	oasys::atomic_decr (volatile atomic_t *v)
	Atomic decrement.
static bool	oasys::atomic_decr_test (volatile atomic_t *v)

Variables
Mutex	oasys::g_atomic_mutex ("/XXX/ATOMIC_MUTEX_UNUSED_LOGGER", Mutex::TYPE_FAST, true)
	To implement atomic operations without assembly support at userland, we rely on a single global mutex.
