Open it with reference to your data.
The more you can reduce your data, the better.
You could start by cutting out portions of your data
which are outside the extent of the last geometry being
inserted (and raising the exception).

Oh, let us also know if passing a tolerance to toTopoGeom
fixes your case (it's an additional parameter).
I still think we need to support the zero-tolerance case.
