Right, think so too.

I disagree.  In my opinion, I want to preserve the order of interleaving 
stdout/stderr outputs.  E.g.

  for i in range(10):
     myFunc(filenames[i])

Now let myFunc output either "File processed fine." to stdout or "Error 
processing file" to stderr.  (Admitted, the messages suck. ;-) )

I would like to know exactly which i's failed.
