Yes.  A module object with an empty dict is not
big enough (on the order of 100 bytes + __name__)
to worry about on almost any modern machine.  Even
if the attached class, function, and code objects
take 10 or even 100 K, that is often not enough to
fuss over (and if it is and they will not be
needed again, delete).  If a module creates a
large multimegabyte private object, it should be
either temporary or explicitly deleteable.
