Running long tasks on heroku as a detached dyno

[hammady]

When running long tasks on heroku as detached one-off dyno as in:
heroku run:detached rake ns:task
The terminal is not connected to the task and all output is sent to heroku logs. This is useful if you are expecting a task to take hours or days and you can't sit and wait for it.
With progress_bar enabled tasks (like sunspot:reindex) monitoring the progress is impossible as the bar will only appear at the end (concatenated in the same line). I think this is because there is no new line character sent until at the very end.
Is there a way to allow this detached mode throw the current progress every minute or a configurable percentage?

This is a workaround I'm doing now:

    pbar.increment!
    puts "\n#{Rake.application.top_level_tasks.first}: <put some descriptive language like the current processed item id>\n"

It will put a new line, forcing the progress bar (if any) to get printed, then leaves room for the next progress bar (if any).
