As the person doing the design for the zone allocator, I
have to say that I was very tempted to start out with
code and just release that.

After some considerations, however, I decided that it
was best to just release the design and ask whether I
had forgotten anything important. Then people:
- asked for 'really needed' stuff like page colouring
and hot lists (that are possible without a major
overhaul, but do require some changes)
- mentioned projects of their own that needed a MAJOR
design overhaul in order to work properly
- thereby prevented the release of yet another crippled,
hack inviting, piece of code

IMHO, the MM subsystem is important enough to start
over with a clean design that allows features like
the above to be added without increasing the hack
value...
