Hi @ldionne 
(I'm finally back from vacations)

Yes, I do think this helps and gets the worst case execution time down quite a lot when the machine is under heavy load.
Without this I could see execution times up to 400 seconds for the testcase, but with the patch I never saw it reach more than 30 seconds, so it looks like it has positive effect.
