Works with 3.2.2:
Python 3.2.2+ (3.2:9ef20fbd340f, Oct 15 2011, 21:22:07)
[GCC 4.5.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from subprocess import Popen, PIPE
>>> p=Popen(["/bin/sh"], stdin=PIPE, stderr=PIPE, stdout=PIPE)
>>> p.stdin.write(b"echo hello\n")
11
>>> p.stdout.readline()
b'hello\n'
Try calling p.stdin.flush() perhaps?
