It is IMO okay to fail when sha256sum is not available and a file is
larger than the available VM, so Emacs runs out of memory, if this is
the situation that worries you.  But these cases should be relatively
rare, and so there's no reason to fail to have this feature in the
much more frequent case that the files are not as large as the
available VM.

If the file can be read by Emacs, even if it's large, then killing the
buffer after computing the hash should not have any adverse effects on
memory usage of that Emacs session.
