the more obscure corners of gobject

[Matthias Clasen <maclas gmx de>]

I have put some effort into completing the gobject api docs, and came
across a number of functions for which I can document what they do, but 
am somewhat at a loss about when one would use them. Therefore, I would
appreciate pointers to any examples for using the following functions:

g_enum_complete_type_info ()
g_flags_complete_type_info ()

g_type_add_class_cache_func ()
g_type_remove_class_cache_func ()
g_type_class_unref_uncached ()
