Inserts multiple objects at the top of the ConcurrentStack<(Of <(T>)>) atomically.

Public Sub PushRange ( _
	items As T(), _
	startIndex As Integer, _
	count As Integer _
)

public void PushRange(
	T[] items,
	int startIndex,
	int count
)

When adding multiple items to the stack, using PushRange is a more efficient mechanism than using Push(T) one item at a time. Additionally, PushRange guarantees that all of the elements will be added atomically, meaning that no other threads will be able to inject elements between the elements being pushed. Items at lower indices in the items array will be pushed before items at higher indices.
