  Useful or not, isn't the basic problem that we haven't been able to
define The Right Thing?  I'd certainly expect a module to be able to
declare in some way that it could not be unloaded, or control how it
gets unloaded.  Perhaps allow Python modules to define an __unload__()
function; when unload() is called on a module, the __unload__() is
called; if that raises an exception, it gets propogated, otherwise the
unload continues if the module still exists in sys.modules.  Not clear
that this would be useful for extensions.
