	GlobalLock (OperationContext *opCtx, LockMode lockMode)
	A GlobalLock without a deadline defaults to Date_t::max() and an InterruptBehavior of kThrow. More...

	GlobalLock (OperationContext *opCtx, LockMode lockMode, Date_t deadline, InterruptBehavior behavior)
	A GlobalLock with a deadline requires the interrupt behavior to be explicitly defined. More...
