destroying GTypeModule object?

[Philip Kovacs <kovacsp3 comcast net>]

Is it ever safe to destroy a GTypeModule object after it is created and 
load() runs
(to initialize/register the plugin types?).  The g_type_module_unuse() 
documentation
states:

"Once a GTypeModule 
<http://developer.gnome.org/doc/API/2.0/gobject/GTypeModule.html> is 
initialized, it must exist forever."

What I am doing is keeping a GList of these objects.   I would like to 
free them
and the containing list in my exit() code because it's an obvious leak.
