 Remember: radiosity+glass+area_light+antialias>=infinite :)

  Gilles said that a workaround is lowering ior, but that could affect
realism of the glass if it is too close. In this case, as it seems not
very transparent, you could make it opaque (it will look cool anyhow!).

  A pain you killed it: but if it was just finishing the glass! The slow
part was almost finished! Oh...
