On the OLPC, we were concerned that the old initscript
infrastructure had a considerable overhead.  Would this
change have a beneficial impact on speed?

I used this benchmark to measure how slow a dummy
initscript is:

  http://www.codewiz.org/pub/true.init

Run it like this:

  time for i in `seq 1 10`; do ./true.init start; done

On a B3/B4 laptop, executing 10 loops takes over
2 seconds.  (and just 1.3 seconds with LANG=C!)
