The last time when I checked this before testing this rev it turned out
that nr_running was always > 1. Traces did only show that the timer
interrupt was still on. I added printks to figure out what was up at that
time which was a bit awkward since the kernel is a bit sensitive about
doing printks in these functions.

Sadly, I am suffering from manageritis these days and probably wont have
the time to get into this again for the next two weeks.
