After some experimentation it seems (assuming the cell has not been removed by a point insertion or vertex deletion) that I can still correctly reference a cell through its Cell_handle after a change to the triangulation. 

Yes it is safe to reference a cell b its cell_handle  if the cell has not be modified by the modifications done in the triangulation.

But if you have a cell_iterator, it is safe for to access the cell behind the iterator, but if the triangulation has been modified

(even without modifying the current cell) the ++ is no longer safe.
