Ok, should we modify the clean command's --all option to 
do a rm -rf build then ?

Patches appreciated ;-) 

Seriously, I think this needs a PEP since it targets a very 
special area: that of maintaining a Python (installation) registry.

Jython already has something like this, so maybe we can learn
from it for CPython... ideally, the registry should live in the
config dir of the Python installation (could produce problems with
file permissions though, e.g. in case someone wants to install
a package in a private dir).
