"import test.autotest", temp_imp failed because the import lock was still held at the test's end (the test assumed it wouldn't be), and then a RuntimeError got raised at the end of the entire suite run because test_imp cleared the import lock as a side effect of trying to test that the import lock wasn't held (but a legitimate import is in progress, so the lock should be held, and the import machinery complained when it found that the lock was unexpectedly cleareed). Also removed the unittest scaffolding. It didn't buy anything here, and the test was raising regrtest's TestFailed instead of using the unittest failure-reporting mechanisms.
