Sending counts back sounds like an excellent idea.

I presume that most firewalls know to stay out of the way of sockets
on localhost, but I'm not all that certain. I don't think that sockets bring
anything to the party that you can't do with stdin/stdout, and my impression
is that sockets would be more complex.

The word filter doesn't do anything for me, although I like xxxRunner.
Maybe ProcessRunner?

I'm not sure I want the two different processes in the same program,
though. It strikes me that the entire process of passing a callback to
Fixture so it can pass back a table at a time simply complicates the
business of file in, file out; I'd rather have FileRunner as a separate,
much simpler program so there's one program with the core, and
another program with the embellishments.

On the other hand, I certainly don't feel strongly enough about it
to argue the point with any vigor.
