Keeping it allows to remove the time_out for experiments, and compiler
would optimize things in anyway, so there must be no code difference
in the end.

Since this doesn't improve things so significantly, I'd rather leave
as is.

And you mixed different fixes (the conversion of printf format) in a
single patch without explanation, too.  Please split, if any.


thanks,
