I don't see what the bad effect of not destroying the varobj if the
frame id is identical is. You might get an errant "value changed"
notification. Other than that, I can't see what you would be gaining.

If we're going to do some extra work to make sure we mark variables
out of scope when their frames are exited, we should get something
real out of it. So far it seems the benefit is only theoretical.
