Constructor worked twenty years ago, too.  But really, what
i always hated is the inflexibility with standards, you could have
atexit, but not atexit_unregister, etc. and so it is with modules.
Anyhow with a dedicated module_unregister call-in a module can
throw away all references it possibly holds explicitly.  That.
