I think there should varobjs that are created from locals which get deleted
when leaving the frame, and ordinary varobjs (which I guess could get deleted
if they aren't globals).  Normally the user won't create two watch expressions
for the same variable but I think that should be his business.  I think it
would be hard to avoid duplication as one watch expression might be a child
object.

In Insight arguments are listed alongside locals.  It might be a good idea to
have:

  -var-list --args-and-locals

and perhaps a field to say which is which.  It seems sensible to list them
all in one window.
