Antoine Pitrou <pitrou at free.fr> added the comment:
You are right that it doesn't work anymore (under Linux too).
Your patch is almost ok. It should raise a ValueError if bufsize=0 and universal_newlines is true (the two can't be satisfied together, since universal newlines implies buffering).
It would also be better to add a test in test_subprocess.
As a sidenote, bufsize=1 (line buffering) doesn't work anymore either, and this can't be fixed without breaking compatibility.
