I have a program occasionally piping commands, one-at-a-time, into
node's stdin which I want to be executed as soon as possible. Like in
the REPL. The commands need to be executed in the same node instance,
as they share state, so I can't just close the pipe and start a new
node for subsequent commands. I don't need the REPL prompt, but it
won't do any harm.

I think that sounds like what I need. But... that's the unstable
branch. Do you have any experience with that? How unstable is it? Is
it likely to crash on me or cause other problems?

So I could just change the console.log() to an eval() in that test.js
and that should work.
OK, thanks.
