You think so?  What happens if someone SetFunction()s OpenLibrary()?
The way that "saves" 6 bytes means that OldOpenLibrary() doesn't
go through the SetFunction().  The "wasteful" way works perfectly,
and is REQUIRED for proper system operation.

I'd be careful who you call smart or not smart.  Smart isn't knowing
how to save six bytes.  Smart is knowing WHEN.
