ecore thread - feedback threads should not be background threads...

if try_no_queue is used - its a thread that clearly wantt to be out of
the queue to run on its own so probably wants to wake up accurately
and thus not be a backgroun rpriority task but and urgent one. ensure
we set up priority accordingly as we didn't before. this should fix
scheduling when under load for vsync
