It's possible to create modules without adding them to the
conventional module namespace, using (make-module).  (And if you know
how the module namespace is implemented, you can remove an existing
module's binding from that namespace.)  So it is possible for a
module's reference count to drop to zero.  I would hope the module
would be gc'ed in that case.
