Strange. I've just double-checked and it works perfectly
well for me, although I haven't traced all the way through
the code paths of the subprocess module: it was a bit of
an educated guess. Just to confirm, I'm talking about this
code running on Python 2.5.2 on Win XP SP2.

import os
import subprocess

f = open ("filename", "w")
  proc = subprocess.Popen ("blah", stdout=f)
except OSError:
  os.close (f.fileno ())

os.remove ("filename")

If I get a chance I'll try to look more closely at the subprocess
code. Could you dump out the code (or the interpreter session
in its entirety) just to make sure there's not a typo or a thinko
getting in the way?
