Research direction
Start with the Streamz.from_textfile entry point and read the linked Tornado discussion and Gitter conversation for the proposed non-blocking approach. Define completion as reading file updates without blocking and emitting only complete lines; the issue does not name files or tests to run.
Written by the indexing model from the issue text.
Description
Streamz.from_textfile could probably be improved to read from files in a non-blocking fashion, and only emit new data once full lines are written. Apparently we'll probably need a separate thread to do this well.
This would make a common and important class of solutions much more robust, and move this project from the "interesting" to "pragmatically useful" status in many cases.

Also, just as an FYI, I'm not working much and have limited connectivity this week.
