If the relative order of the messages to stdout and
stderr is important, how come it's better to completely
lose the relative order by placing them in separate
files?  If we are to remove messages from the console
then surely they must be interleaved properly in a single
file.  If a way can't be found for doing this I don't
see how we can change the present system - or have I
missed something?
