I think the a position A is stored as staff number, measure number,
object number.
This means that if you insert an object in the same measure as A then
when you PopPosition you will be at the object before A. If you insert a
measure before the measure with A the cursor will be in the measure
before the one containing A and so on. Basically, it is not easy to use
for the case where insertions/deletions are happening before A.
I don't think there is a trivial fix. 
We could store an object id and search for it, which would take a medium
amount of coding (the minimum would be to generate such an ID in the C
routines and let scheme query for the ID of the current object).
