* Allow SmartThreadPool to be initialized without setting max stack size (like the original implementation)

Browse Source 
* Only initialize Util's SmartThreadPool if it is actually being used
* No longer initializing Util's SmartThreadPool with a custom max stack size. From MSDN: "Avoid using this constructor overload. The default stack size used by the Thread(ThreadStart) constructor overload is the recommended stack size for threads."
