Sorry, it seems, that I ripped the thread... anyway, its the problem I'm
describing. I was given the advice to add idle=poll to record idle
times. I can't actually confirm that it is recording idle times now,
because I can't find a way how to list the results so that they will
appear assigned to respective parts of the binaries I'm interested in,
and that's the basic problem.
