Heh. You think Xen's code is virulent? I wouldn't go that far, although it has 
infected quite a number of people. :-)

Seriously: Unfortunately I can't reproduce the bug properly ATM, because the 
recent builds don't work properly for me... But as far as I can see (i.e. 
just dom0 testing) something seems to be wrong, but I guess it is something 
outside the core-scheduler, as the problem doesn't happen with my older (bk 
repo) version, and from that to the current code nothing has changed (at 
least not inside sedf). But that said, I think I should introduce measures to 
make the scheduler invulnerable against that kind of external fault!
