A Singleton Macro that swaps method implementations at runtime so that only the initialization portion will require syncrhonization (lock). - Specifically it uses method_setImplementation() to dynamically replace the sharedInstance access method with one that does not instantiate a new object and thus does not require @synchronized. It is based on the work here: http://cocoawithlove.com/2008/11/singletons-appdelegates-and-top-level.html by Matt Gallagher But changing the implementation to use method swizzling as described here: http://googlemac.blogspot.com/2006/11/synchronized-swimming-part-2.html by Dave MacLachlan of Google.
