Of all the file descriptor types, I’ve been having trouble with DTYPE_MEMFD. Even though it exists in the NetBSD source code, the corresponding header on an actual installation seems to be missing this definition. I’m not sure how to handle this properly—whether to ignore it during tests or not include it at all.
