Well, i did see that the menu and scrolled window in testgtk show this
behavior, there don't seem to be any notbeook item in the testgtk menu though
in the version i use (1.2.0-3, i know there is a new version around, will
package it nextly).

Both of these functions are quite big, using references and Object
creation/destruction. I know that reference creation can trigger a garbage
collection, but i don't think it would really be influencing things here,
since it is only small programs. I am not strong enough in ocaml performance
to give any additional, so i will CC this to the lablgtk list.

Also, note that you can get a noticeable increase in speed if you try to
compile your program to native code with ocamlopt, but my trying this with
testgtk was not successfull.
