Seth Hillbrand 8506cdf3ae Avoid numerical dereference of selections 
The SELECTION is a std::set.  Numerical dereference of item n is O(n) as
the iterator is not random access.  Therefore, a for loop using
numerical dereference is O(n!) and quickly slows.

We avoid this by storing items to remove separately while iterating and
then removing the items after we complete.
