Oleg, i'd like to make it sure that the role of Gregory Haskins is clear 
here: he submitted some new infrastructure into the -rt tree, and i 
reviewed that but found it quite complex and duplicative and suggested 
him to think about enhancing workqueues with priority properties - which 
might or might not make sense.

It is not the intention of the -rt project to pester any upstream 
maintainer with -rt issues if that upstream maintainer is not interested 
in it ... so please just forget about all this if you are not interested 
in it, we'll sort it out within -rt. Thanks,

	Ingo
