Window cleanup

I need to know when a user browses away from my window so I can perform internal cleanup. I have tried adding a desktop listener, using a UILifeCycle listener, a ComponentCtrl, and just about everything else that looks like it could tell me when the user leaves a page without explicitly clicking something that tells me they are leaving.
I do get the DesktopCleanup.cleanup callback which tells me the name of the last page, but I don't see a way to get a handle to the specific instance.

Otherwise I have failed to ever get a callback when somebody leaves my page - they can do this by clicking on one of several buttons or by simple using back buttons or just going to a new URL. I am using a GenericForwardComposer to handle all of my callbacks from the .zul page.

Can someone please point me to a sample for how to get a callback when a Window is no longer visible (onClose is not called since nobody clicked a "close" button). I tried onHide but that doesn't work - I think since nobody calls setVisible(false).

Thanks
