 issues with long waiting times?

 The affected section is Language, and yes, is specially noticeable in
 XO-1, and gets worse with more languages.  By the way I have ongoing
 patches for #4327 to improve this specific section.  Happens too testing
 the patch for the proposed Background feature:

 Looks like a regression, works without the patch.

 Good catch!  Yes I was checking and this happens because of the while loop
 that calls Gtk.main_iteration() [1] in that section model.py .
