IMHO detaching the toolbar is a red herring here.

Yes, there on big valid reason to disable detaching the toolbar: it
seems that detaching the toolbar is disabled by default by (almost?) all
Gtk+ applications.

The ticking time bomb is actually using an emacs compiled with the Gtk+
support in conjunction with multi-tty.  emacsclient + kill emacsclient +
emacsclient results in a crash.

IMO we need at least a big fat warning in NEWS (or some other very prominent
place) with a reference to the Gtk+ bug to make users aware of the
problem.  We've had many bug reports about this, we'll only get more
after the release.
