It will lock on the instance monitor (ie. 'this'), the static object 
monitor (ie. Classname.classinfo), or the global monitor, depending on 
context.

By the way, I agree that it's a Bad Idea to lock on an object that 
internally locks on 'this', but I'm not certain that it's something 
worth having the compiler enforce.
