Not '\0' delimited, but I think a similar case to what you mention is
'cksum -c':
$ (ulimit -v $(($(numfmt --from=iec 5G) / 1024)); cksum -c /dev/zero)
cksum: /dev/zero: read error
In this case mmap fails with ENOMEM, but for some reason that
information is removed from the error. I'll have a look at that later.
It could likely be handled similarly --files0-from, i.e., read the
maximum file name length, max checksum length, and some extra
characters based on the format we are using.
