Log: Remove this test because it doesn't make sense anymore.
In the default branch (implementing 2.7), the test checks that, even
though the script first writes to sys.stdout, stderr is output
first. This works because both streams are buffered and, at
interpreter shutdown, sys.stderr is flushed first.
The order in which sys.stdout and sys.stderr are flushed isn't
determistic if running on Python 3.x. Because of this, the test was
changed in the py3k branch (at the time trying to implement Python
3.2) to check that both streams are always line buffered. However
this assumption is false. Since Python 3.0 sys.stdout and
sys.stderr are line buffered by default iff connected to a TTY or
set otherwise unbuffered.
