Ideally you should use two actors. One for reading the list of files, and one for actually reading the file.

You start the process by simply sending a single "start" message to the first actor. The actor can then read the list of files, and send a message to the second actor. The second actor then reads the file and processes the contents.

Having multiple actors, which might seem complicated, is actually a good thing in the sense that you have a bunch of objects communicating with eachother, like in a theoretical OO system.

Edit: you REALLY shouldn't be doing doing concurrent reading of a single file.
