* Fix #811: new socket server to receive pid and port for subprocesses * Install test dependencies from test_requirements.txt on Travis * Multiproc support can't handle os.fork() as implemented. On Python 3.4+, use set_start_method('spawn') to ensure that multiprocessing module doesn't use fork. On lower versions, skip the test. * Restrict the multiprocessing test to Windows for now.
