title: using TBB for non-parallel tasks
body: <p>I want to get a thread-pool behavior using TBB. But whenever I read documents about TBB they always talk about parallel-for, parallel-dowhile etc. In contrast what I need is a main thread to assign tasks to a thread pool so those tasks will be executed 'on their own' - execute tasks asynchronously. Tasks here can be event handling for a GUI. </p>
  
  <p>Is the TBB task scheduler appropriate for such behavior? The impression I got from task scheduler is that it's only beneficial if I have tasks that can be broken down and executed in parallel to each other.</p>
