I don't think so.  It's still a race condition in between choosing an
apparently existent directory and then making use of that directory,
isn't it?  I think "/" is the only place certain to exist and not go
away.  It's also the simplest approach.

`sha1-string-external' is another place this comes up.  In that case the
operation is completely unrelated to any directory, and so really should
go to "/" so as to be independent of default-directory or whether that
dir is coming or going.
