the order of the writes isn't preserved.
How can I get this to be the case?
You'll need to flush the std{out|err} or set them unbuffered; or you can
just forget about relying on std{out|err} being ordered per write-order.

Hi All,
I have this simple function:
def execute(command):
process = Popen(command.split(),stderr=STDOUT,stdout=PIPE)
return process.communicate()[0]
..but my unit test for it fails:
from testfixtures import tempdir,compare
from unittest import TestCase
class TestExecute(TestCase):

You probably just need to flush stdout and stderr after each write. You
set them up to go to the same underlying file descriptor, but they still
each have independent buffering on top of that.
Okay, but if I do:

Interesting, but do these assertions still hold
