- the number of packages waiting on the package to be build

- the number of depends on the package (as a general measure of
  importance) maybe weighted by priority of the packages.

- the number of uninstallable packages caused by this package

- the number of (RC) bugs fixed by the upload

- the age of the package (to some degree) [Building a 3 month old KDE
  is more important than yesterdays bash]

- the compile time / disk usage of the package (small builds first)
\ the cpu/disk power of the buildd wanting to build something
  [don't build qt-x11-free on a 68030, use the 68060]

- build packages with similar Build-Depends in sets [give 3 kde
  depending packages to the buildd. Look at the top package and find
  X-1 similar Build-Depends under the first 3*X needs-build packages]


Most importantly the wanna-build should never tell a buildd to build a
package that can't be build anyway( due to its Build-Depends).
Installing the build-depends for an hour just to figure out that one
of them isn't new enough is a big waste (OK, the buildd shouldn't do
that but check that first). Its wastefull to have the buildds check
and recheck that every so often instead of the wanna-build doing it
once.
