On gerrit you had some code where the destructor had : if (deletingStatus) cleanUpAndDelete
we need this in case one shuts down during the 1 minute after removing an applet?

This will presumably require every look and feel applet/container interface to implement some sort of visible: status != AwaitingDeletion ?

What would happen in the following scenario:
 - My laptop is plugged in to the mains
 - I delete my battery applet
 - I unplug my laptop  (causing the battery applet to call setStatus() )
 - 
 - The Item status would change and it would reappear? but with the timer still running?
