Minor correction:  No it doesn't.  It constructs a WorkerLocalStorage 
object in a regular class method in the thread from which 
workerLocalStorage() was called.  It does evaluate the lazy parameter 
more than once, but all the multithreading stuff happens **after** 
workerLocalStorage() returns.  I still see your point, though.
