This doesn't seem to work.
>>> b = io.BytesIO()
>>> p = subprocess.Popen(["ls", "-l"], stdout=b)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib64/python3.2/subprocess.py", line 711, in __init__
errread, errwrite) = self._get_handles(stdin, stdout, stderr)
File "/usr/lib64/python3.2/subprocess.py", line 1112, in _get_handles
c2pwrite = stdout.fileno()
io.UnsupportedOperation: fileno
I think stdout and stderr need to be actual file objects, not just
file-like objects.
