Ok. I am not familiar with scheduling stuff but I hope you can fix those 2 issues. I have no objection with this patch and I prefer Jeff or kito make the decision for this patch.

The second one is fixed on my local branch, the first not yet because there is more to it still. The second one is more due to pressure-aware scheduling and I'm going to add it to the commit as well as the PR to the commit once this is verified. Regards Robin
