For realization - simply utilize multiprocessing.Pool class. Notes: 1. Of course, tests can't run simultaneously in same TEST_DIR. So, use subdirectories TEST_DIR/testname/ and SOCK_DIR/testname/ instead of simply TEST_DIR and SOCK_DIR 2. multiprocessing.Pool.starmap function doesn't support passing context managers, so we can't simply pass "self". Happily, we need self only for read-only access, and it just works if it is defined in global space. So, add a temporary link TestRunner.shared_self during run_tests().
