Thomas Veerman 827daf1fca Make test40 behave
Make test40 behave better. It should create its own subdirectory to
conduct its tests and should not write to /tmp. Also, the master-slave
terminal pair it tries to open might be in use; it should try to obtain
another pair. These changes allow the test to be run multiple times
simultaneously from different paths (to test select() more intensively).
