Description

The Ray nondeterminism tests are failing on
https://github.com/ray-project/ray/pull/436 (moving to Arrow's Tensor serialization code).

This might mean that there is some nondeterminism (like uninitialized memory) in the IPC file written by the Arrow Tensor serializer. I'm investigating it now, please let me know if you have an idea what the problem could be.
