It may have been Michael or Peff (CC'ed) saying that it could break
some builds as the timestamps on the files might not always be ordered
in the same way.

Now perhaps parallel checkout could be activated only if a config
option was set. (Yeah, I know it looks like I am very often asking for
config options.)

Thanks for your work on this. It is very interesting indeed.
