There are ways to circumvent it.  For one really ugly way, look in
jni.cc -- we reference count JNI local and global refs.

Having a nice API would be good.  I'm afraid it isn't on my to-do
list.  But if you want to write something, the patch list is always
open...

That's true.  If the Gtk reference became the only reference to the
object, the GC would think that it had died and would collect it.
