Some months ago, I started work on a new fairsched patch for 2.5 kernels
with o(1) complexity ( goto http://wind.cocodriloo.com/~wind/fairsched/ ).

I was stalled, but perhaps someone else, with better kernel skills,
could take a look a try to make it work.

Mind you, this may be important in order to get a good kernel for the host
side.

1. Dado un programa, siempre tiene al menos un fallo.
2. Dadas varias lineas de codigo, siempre se pueden acortar a menos lineas.
3. Por induccion, todos los programas se pueden
   reducir a una linea que no funciona.
