Please add a configure option to explicitly enable it.  The reason is that I 
already run it, and starting it twice breaks it, and I do not want to use your 
version because it doesn't start a window manager which is needed for some 
tests.  But starting a window manager is again "complicated". When using twm, 
you'll have to make sure that the placement of windows is automatic, when 
starting metacity, it might be necessary to start it with a dbus-session, and so 
on ... Not sure if you want to add all this to the configury.
