Since you are calling this a 1.6 regression, why are you not comparing
against 1.5.6?

You might have mentioned how long it takes this checkout to run? I am
running checkout from a box in the CollabNet network and it is still
taking forever.

On Windows, with 1.6.0 RC2 on a box in CollabNet network, this
finished in less than a second.

I need checkout to finish to run the rest. I will update you when I do.
