+ * This function makes a copy of the reader. Since readers use
+ * positioned reads with pread(), this allows you to have multiple
+ * readers with the shared file descriptor. This uses dup() to create
+ * another file descriptor.
+ *
+ * Returns: (transfer full): A copy of @self with a new file-descriptor.
