I am no expert but I quickly looked at the sources and this doesnt seem to be
possible to be set (if its possible please someone tell em).
what scheduler are you using? if you use the other one can you reproduce

can you try this patch (added to the pathces you already have):
the locking there sucks, I'll have to revisit it together with
the LIST magic ;(
