New description:

 from #1311:

 FWIW, holding Alt down in my F11 sugar-jhbuild environment seems to behave
 like an auto key repeat, it is as if the entire set of icons are being
 continually re-generated/drawn rather than just on key down, key up. CPU
 load goes through the roof, and if I hold Alt for 3-4 sec or more the
 machine is locked up for 7-8 seconds.
