** Description changed:

  Binary package hint: thunderbird
  
  thunderbird might cause unnecessary disk activity. It is important for
  laptop users to reduce unnecessary disk-activity because the harddrive
  head might be parked or the drive might be spun down.
  
  If thunderbird tries to get new messages and there are no new messages
- there is still some disk activity.
+ there is still some disk activity. IMHO there should only be
+ diskactivity when there are actually new messages.
  
  If people would make thunderbird check for new messages each minute this
  means that each minute thunderbird is accessing the disk even if there
  are no new messages.
  
  This might be one of the contributors to the famous Load_Cycle_Count bug :
