Properly check for consistency with the third argument of
compile() when compiling an AST node.

The buildbot "x86 W2k8 trunk" seems to hang in test_socket.
http://www.python.org/dev/buildbot/trunk/x86%20W2k8%20trunk/builds/255/step-test/0

Temporarily increase verbosity of this test.

Still investigating on the hanging test_socket.
the test itself doesn't do anything on windows, focus on setUp and tearDown.
