In some cases it would be desirable that other processes are notified of a 
config file change.

e.g. Open 2 KWrite processes.  Change the orientation of the main toolbar in 
the 1st process.  After .5s KMainWindow, will call KConfig::sync().

Then open up a new window in the 2nd process (you might have to type something 
to force CTRL+N to work).  The new window's main toolbar's orientation is 
still the old one.  But if you open a new window in the 1st process instead, 
the new orientation is used.

IIRC, this is because the KConfig object in the 2nd process isn't notified of 
the change.

In KolourPaint, I solve this using kapp->config ()->reparseConfiguration () 
before every config read.  But this is hopelessly inefficient.  Automatic 
interprocess config change notification or interprocess KConfig objects would 
be a nice solution, IMHO.
