Hello, Python 3.1 ignored the PYTHONUNBUFFERED environment variable and the '-u' switch (which do the same thing): stdout remains buffered even when the flag is raised. To reproduce, run: > python3 -u -c 'import time, sys; sys.stdout.write("a"); time.sleep(1); sys.stdout.write("\n")' You can see that it first waits a second and then 'a' is printed. I'm using Ubuntu 9.10. Tested this on both the 3.1.1 installed and svn checkout (revision 79345). This follows a bug report: https://bugs.launchpad.net/dreampie/+bug/545012 which was reported on win32, so the problem is there too.
