also.. "what is a bugfix" is an interesting thing... for some things it's very easy.
For others.. it's really hard to draw a solid line where bugs stop and features start.
(for example, is a missing cpu id in oprofile a bugfix ("oprofile doesn't work") or 
a feature ("new cpu support"). This one is one of the more simple ones even...)
