This has made me to realize, that I was having a problem with SCHED_ULE 
that I was not aware of until now. WOW! :)

Every scheduler has some problem, some fail here some fail there. I am 
confident, that the case that Steve Kargls has reported will be resolved.

You never heard of the "People's Republic of Berkeley"? :)

As for commiter access, this sort of comments trigger the system 
administrator in me. I have seen enough people, who for the lack of 
other excuses always use "but I don't have enough RIGHTS!". I am evil, I 
know....

Here is now it works:

If you see an problem and have a solution: go fix it. Many will be grateful.
If you can't fix it, but have an idea how to fix it, share it. May will 
be grateful.
If you can't fix it and don't have any idea, just say "there is a 
problem" and stop there. There are many, many, many like you who just 
hold their breath.

We all learn, every day.
