In this initial version, there is only one local test which actually only checks if the 9pfs 'local' device was created successfully. Before the 9pfs 'local' tests are run, a test directory 'qtest-9p-local' is created (with world rwx permissions) under the current working directory. At this point that test directory is not auto deleted yet.
