Aaargh! Of course I was looking at the annotate output, which said Nov 9, 
2004. But this is just the last change to the signature of the function!

So, AFAIK Sep 13, 2001, is the correct date, and 0x070900 is the version.

There might well be a substantial overhead involved. I haven't measured it, but it seems reasonable to assume that duplicating a handle is implemented using a shorter code path than creating a handle all over again.
