Yes. But some things might not be garbage collected until the shut down
process has already started garbage collecting other modules and code
that your __del__ method relies on.
I believe that __del__ has become more reliable recently and will now be
successfully called in situations that it didn't previously be called,
but the interation of garbage collectors with destructor methods is
still fraught with difficulties.
