I question how meaningful that particular case is. When you start with 
something that's not XML, and then generate something that's not XML, it 
doesn't really match a typical usage pattern.

There's also the concern that it's not just the application being 
benchmarked. It's the documents. Optimizations for one style of document 
may not apply or even have negative effects for others.

For instance, so far I have not been able to reproduce your result that 
short-circuiting nonrecursiveCopy (now copyChildren) was noticeably 
faster than just letting it run out. In my tests it ranged from a couple 
of percent faster to a couple of percent slower from run-to-run.
