I'd love to be able to experience the speedups of gcc-4.4 and by rights I 
should be able to - my last "rip gentoo apart and put it back together again" 
stunt needed an emerge -e world to fix it all.

But, and this is the bit that makes me cry, the slowdown from KDE-4.4.5 has 
obliterated all that advantage several times over.....
