`SpinCriticalSectionLock` class	Scope guard that holds a critical section, spinning before it suspends.
`SpinSemaphoreLock` class	Scope guard that holds one permit of a semaphore, spinning before it suspends.
`Suspendable` class	Records a suspending task as waiting and then re-checks the primitive's condition.
`SuspendableBase` class	Keeps the tasks suspended on one synchronization object and resumes them.
`SuspensionKind` enum	How many tasks may be suspended on one synchronization object at the same time.
