        # `test_early_readchild_exit` when the writing process is a
        # child process itself (above, the write process in the initial
        # process). Since gipc's child process creation
        # routine messes around with signal handlers, this test makes
        # sure that SIGPIPE is ignored in the child and that a
        # failing write attempt (after early read child exit) results
        # in an exception raised in the writing process.
