I'm not instrumenting the code but using a stopwatch so timings are a
bit rough.

The test:
- reboot the machine
- wait that jfss2_gcd_mtd0 finishes hogging the cpu
  (around 50 secs from when the shell is displayed)
- go to the listview
(*)
- for every activity (one at time), from the drop menu->start and take
the time until the full window redrawn

- do it again from point (*) if you want to see the difference between
first startup and 'warm' startup

I also use to gather stats with Picker while doing the test, to see
what processes are taking more cpu time; it also helps to catch
conditions where activities are fully redrawn at time x but really are
fully loaded at x+20sec (easy to see in etoys and browse).

Are both first and second launch timings needed ?
