I submitted an equivalent patch for Gtree which should be considered
after we have decided on the GHash API. IMHO the GTree API should
indeed be very similar to the GHash API. This makes it easier to use
both as specialized implementations of a more general data container.

A destroy notifier does not make much sense for GLists since they lack
the concept of a key.

I guess you have a special reason for this configuration, since Gtree
also allows a linear list-like access using g_tree_traverse. Anyway, 
the proposed API will probably make the usage of trees and hashes more 
intuitive
