[issue4680] Queue class should include high-water mark

Roy Smith added the comment: I'm suppose you could implement this in a subclass, but it would be inefficient. You'd have to over-ride put() and get(), call qsize(), then delegate to Base.put() and Base.get(). A cleaner solution would be in the C implementation of deque, in Modules/collectionsm
