title: Sort of scheduler
body: <p>I need to implement something. Something that could do some certain task in my program. For example every ten seconds, write something into a log in a file.
  Of course it suppose to run in a background thread.</p>
  
  <p>Where should I dig? I am not so familiar with multithreading. I've heard about BackgroundWorker class, but I'm not sure if it is appropriate here..</p>
