Description Petr Nejedly 2005-03-14 13:16:34 UTC 
getStatusLineElements registers a lookup listener on StatusLineElementProviders
On each change, the listener calls (from AWT) decoratePanel(), which calls back
to getStatusLineElements and registers another instance of the listener.
So each time there is an event from the default Lookup about such a change,
the number of listeners grows exponentially and the time to process them as well.
You can probably easily trigger the problem by reloading a module.
