No, but I don't see where either algorithm would have noticeably 
different memory access characteristics, so it shouldn't matter. In both 
instances, you have to fetch the pre-hashed pointer.

Honestly? I doubt that the difference would be noticeable.

It would be interesting to write a "full" test, but I'm not sure I'd 
trust anything outside of an actual application (and then, how do you 
test performance? :-) ), as a realistic allocation pattern is needed.
