Rolland, i feel that such changes are going to be quite intrusive for
HEAD now as we are close to 4.6.1. I just thought that as a first step
you might want to create a new branch where you'll implement what you have
in mind. When the code is mature enough it could be merged in HEAD. I
guess the code will change a lot in the beggining until the concept is
clear - I think this will cause a lot of confusion. The branch will also
give, those people interested in the new code, full access to the modified
tree. This is much easier than spreading your changes through a set of patches.
