I don't particularly like that. We're obviously talking about only some 
of the "core functions" (and it's debatable whether Grep is one of

You stated that. I never agreed. I just mentioned that it has an 
advantage (each result is displayed as soon as the process finds it), 
but we should be able to implement it for xref as well, using generators.
