[[tschwinge]] once worked on this, posted patches to [[mailing_lists/libc-alpha]]. This works needs to be resumed and finished. Add tests from Linux kernel commit messages for `t/dup3` et al. Validate completeness according to or a similar list. In an interesting point is made: *you [may] want some [[unix/file_descriptor]] to still be open if 'exec' fails, but you don't want it to be open after the exec succeeds*. [[I|tschwinge]]'m not sure whether our current `O_CLOEXEC` implementation adheres to that.
