battery life need careful thread planning.

pattern like :
  while (true) {
      if ( condition ) { doSomthing; }
      else  Thread.sleep(1000);
  }
would wake up the thread every one second.
This hurt the battery a lot.

Should have used object.wait / notify for this.
Freenet source code have lots of pattern like this.

Another (bigger) issue is harddisk spin down, we keep
accessing the disk, there is no chance for spinning down.
-- there is no fix for this. we have to access the store.
