Does anyone know what the call to sanitize_stdfds() is good for? I
tried searching the mailing list, but the discussion on the patch that
introduced it seems to only discuss how to implement
sanitize_stdfds(), not why...

I understand that it might be beneficial in the --detach code-path,
but how can stdint, stdout or stderr be closed in this code-path?
