For whatever it may be worth, I intend to continue supporting the traditional
interpreter VM to the best of my ability for the forseeable future. I also
intend to help as best I can to support Cog and hopefully to help merge
code bases and reduce redundancy where possible. Finally, I think that the
work Igor is doing for automated builds is very valuable.

Let's be glad for the progress that is being made with new VMs and new
build processes, but please do not assume that this progress comes at
the expense of all that has come before. It just ain't so.
