Another new test using "from test.test_support import ...", causing

subtle breakage on Windows (the test is skipped here, but the TestSkipped
exception wasn't recognized as such, because of duplicate copies of
test_support got loaded; so the test looks like a failure under Windows
instead of a skip).
Repaired the import, but

        THIS TEST *WILL* FAIL ON OTHER SYSTEMS NOW!

Again due to the duplicate copies of test_support, the checked-in
"expected output" file actually contains verbose-mode output.  I can't
generate the *correct* non-verbose output on my system.  So, somebody
please do that.
