For FINIALIZE_INSTANCE, you need to subclass with Glib::Object::Subclass
(or Glib::Type->register).  But that doesn't seem to be necessary.

How about calling the package Gtk2::Ex::GCPool or similar?  I think it
would also be cleaner if you separated the pool class from the custom
Gtk2::Gdk::GC class.  That is, have Gtk2::Ex::GCPool->get bless the gc
into Gtk2::Ex::GCPool::CustomGC and put the @ISA mangling and DESTROY in
that package.
