Except when 260+ packages need updating as it happened with the last KDE 
upgrade.  I had a cursory look, but I missed some USE flag changes (scanner, 
rdesktop and vnc I think) which started removing packages and libraries.  
Other flag changes may well have added packages that I didn't need, but didn't 
have the time to go through the lot at the time.
