Yes, they are supposed to behave like normal perl objects, which die when the
last reference goes away.  A wrinkle is that references held by gtk objects
count, so you can have no perl references to object, but it will still live
because a C object has a reference to it.  (This is A Very Good Thing.)

Be warned, however, that closures connected to signals, as well as user data
parameters, take references on these objects, so it is very easy to create
reference leaks by sloppy coding.
