title: AsyncTask, RejectedExecutionException and Task Limit
body: <p>I am fetching lots of thumbnails from a remote server and displaying them in a grid view, using AsyncTask. The problem is, my grid view displays 20 thumbnails at a time, so that creates 20 AsyncTasks and starts 20 executes, one per thumbnail. </p>
  
  <p>I get <code>RejectedExecution</code> exception in my code. I recall reading somewhere that there is a limit to number of tasks that AsyncTask can have in its queue at a time, i might be hitting that. Was this bar lifted? </p>
  
  <p>Is there a way to increase this limit? Is it safe to just ignore this exception?(by having an empty <code>catch(RejectedException e){}</code> block?)</p>
  
  <p>I am running this code on Android 1.6 emulator and the API level in my code(minSDKVersion is 3).
