I think you have to figure out for yourself a policy of when you
get rid of that object. For instance, you could get rid of it
when the last GtkIMContext from your module was destroyed. Or in some
timeout 5 minutes after the last GtkIMContext was destroyed or ...

But there is no way that GTK+ can unload your module if some instance 
of a type created in it is still around. That would just lead to a
segfault.
