First off (perhaps in case you didn't notice), we're doing blazing fast.
As a matter of fact, a task with 1000 of packages, running for the
second time, can complete within only hours.  If you still think this
isn't fast enough, consider that 1000 packages actually are 1/n-th part
of the whole repo.

Because what we do is "purely functional" builds, with no exceptions.
Whenever a packages is getting built, its build environment is
remembered.  On the second run, would the environment change, the
package must be rebuilt.  "The envorinment" = "packages installed
into build chroot e.g. on behalf of BuildRequires".

Consider then you uploaded a package called "foo", which is a
prerequisite for python-module-foo.  But python-module-foo has been
rebuilt with python-2.6; it is busy wating.  So we don't want to trigger
the chain of rebuilds by allowing... oh well...
