The interactive interpreter in IDLE does not reset its compiler __future__ flags when you restart the shell.
To verify this, type into the shell:
>>> from __future__ import barry_as_FLUFL
>>> 1 != 2
You'll get a syntax error. Restart the shell and type
>>> 1 != 2
A syntax error still occurs.
The ModifiedInterpreter class in PyShell.py ultimately relies on codeop to mimic the interactive prompt. The codeop module was created specifically for remembering __future__ flags for subsequent commands.
The provided patch stores the flags of the interpreter when it first initializes, and then restores them in "restart_subprocess". It's a patch against 3.2.2.
