  this looks good, except for the two log messages. They seem to be
superfluous because first the callers of run_task(, uint) already print
mostly the same message, and the given code guarantee's that whatever
is printed anyway. Further, a single invocation of run_task will now
trigger three messages basically telling the same.

So I would prefer if these messages were either moved to trace level,
or just removed.

Thanks a lot for your patience with me, :)
