combining stdout and stderr

[Skaperen]

i want to combine stdout and stderr on the same output so both can go over a single pipe. the buffering of stdout can mess up the line ordering. i don't want to solve that be eliminating buffering. i want output to either to be buffered in a common buffer. it seemed to work when i did

    import sys
    ...
    sys.stdout.flush() # not necessary if before any output
    sys.stderr.flush() # i have hit cases where it was buffered
    sys.stderr = sys.stdout
    ...

is there a more appropriate way to do this?
