Type	Name	Description
bool	CancelWait ( FWaitEvent* Node )	Step to run by normal workers if they detect new work after they called prepare wait.
bool	CommitStandby ( FWaitEvent* Node, FOutOfWork& OutOfWork )	Second step to execute when no more work is found in the queues.
bool	CommitWait ( FWaitEvent* Node, FOutOfWork& OutOfWork, int32 SpinCycles, int32 WaitCycles )	Second step run by normal workers when no more work is found in the queues.
void	ConditionalStandby ( FWaitEvent* Node )	Immediately goes to sleep if oversubscription period is finished and we're over the allowed thread count.
void	DecrementOversubscription ()	Decrement oversubscription only, any active threads will finish their current task and will go to sleep if conditional standby determines we're now over the active thread count.
void	FinishShutdown ()
void	IncrementOversubscription ()	Increment oversubscription and notify a thread if we're under the allowed thread count.
void	Init ( uint32 InThreadCount, uint32 InMaxThreadCount, TFunction< void()> InCreateThread, uint32 InActiveThreadCount )
bool	IsOversubscriptionLimitReached ()	Is the current waiting queue out of workers.
int32	Notify ( int32 Count )	Try to wake up the amount of workers passed in the parameters.
void	PrepareStandby ( FWaitEvent* Node )	First step to execute when no more work is found in the queues.
