     8  // descriptor 3 and that no other descriptors are open.
     9  // This is not done via TestHelperProcess and GO_EXEC_TEST_PID
    10  // because we want to ensure that this program does not use cgo,
    11  // because C libraries can open file descriptors behind our backs
    12  // and confuse the test. See issue 25628.
