Hello
In my application I use the standard swing "undo" system. Some
UndoableEdit take very little memory and some take a lot. Instead of
specifying a number of undo _levels_, I would prefer to specify a max
amount of memory dedicated to the undo system (for one given UndoManager).

How could I implement this? Can I construct my UndoableEdit and then
measure its size and add this memory value to the UndoManager which will
drop the oldest edit if the memory is above a threshold?

Thanks for any advices
Phil
