And...of course, it would be rally nice that this is done by implementing the protocol #cleanUp:� and #cleanUp

Check issue http://code.google.com/p/pharo/issues/detail?id=2130

At some point, we will be able to do Smalltalk cleanUp� and this propagate the message to all clases.

For the moment, just implementing your cleaning in those methods, and calling them from cleanUpForRelease would be enough.
