A bug, unless someone steps forward to fix this, it'll probably be a
problem for a while.  What needs to be done (IMHO) is to have a per
module dynamic dtor list and run it at module dtor time, and put in a
hook for users (or the system) to call before the unload.

All the global dtors as well as the one atexit style dtor in decl.c
need to use the same mechanism.

This has been discussed before on this list, you might try the
archives for more information.
