scripts without modifying either the distutils installation or the
setup.py scripts of packages with which the new commands will be used.

leaks.

the case of __del__ resurrecting an object.
This makes the apparent reference leaks in test_descr go away (which I
expected) and also kills off those in test_gc (which is more surprising
but less so once you actually think about it a bit).

unused (as it is meant to be), but now the compiler thinks it is worth
*something* by having it incremented.
