You understand that in order to change the target file, the
filesystem needs to be writable, right?

It's so fast that you never even realized that the moreutils
version uses a tempfile! Have you complained to GNU
about `sed -i` using a tempfile?

If you don't want the extra writes, mount /tmp as a tmpfs.

Perhaps. I still wouldn't know how much to map, so I'd need
mremap, and from the manpage:
This call is Linux-specific, and should not be used
in programs intended to be portable.
If you write a portable patch making use of mmap, I'll
definitely consider applying it.
Fundamentally, sbase is about simplicity. The current version
works well in every circumstance, on platforms as odd as
lunix, and is absolutely trivial to understand.
