Exception handling causes huge overhead, it caused an overhead of about 1Mb / 
process for KDE applications when I last measured it (about a year ago). I 
don't think this has changed much with gcc 3.0.

You can use exceptions in your own code though, as long as you don't throw 
any exceptions through Qt or KDE code. (Watch out for signals/slots)

Your application will crash or abort when you attempt to throw a signal 
through Qt or KDE code (when it is compiled with -fno-exceptions)
