Subject: updating an RJS template _while_ executing a method

I have a method doing I/O stuff which takes quite a long time.
While this method is processed,
I want the user of my tool to be informed of the current execution state.

For example,
if the method opens a file,
I want my RJS template to render a message such as "opening file XYZ...",
if the method changes to a directory, message would be "cd to ...".

As far as I can tell,
RJS templates are rendered AFTER the corresponding method is executed.
But I want them to run (sort of) synchronously.
Or at least have a way to trigger messages while a method is executed.

Cheers,
  Tom.
