What about simply waiting for the response from GDM before proceeding
with the gnome logout ?

So, if it is really fast, there should be no problem in doing it at okay
time.

Yep, this sounds reasonable. When the timeout is reached, it will
logout, but there is no way to ensure that GDM will effectively logout
or not, right ?
It would be nice if the timeout was configurable, as a gconf hidden option
only maybe. I guess it will only take longer time when you are on
non-local sessions, and in this case i doubt people will want to enable
this feature anyway.
