Good idea. These hacks are the best argument for applying the
change, IMHO. I made a quick review of Lib modules using __del__:

    tarfile: looks not safe
    tempfile: goes through elaborate motions to avoid globals
    threading: yikes, I didn't attempt to decypher this one
    shelve: probably not safe
    dumbdb: avoids globals, easy to remove hacks
    _pyio: try/except can be removed (hopefully)
    urllib: avoids globals, easy to remove hacks

Will try to cook up a patch in my copious free time.
