Ok I've found the problem: the last argument to `MXCreateCachedOp`, `thread_safe`. By setting that to `false` instead of `true` the backward is computed correctly. This argument is always `false` in the executor python interface. It sounds very surprising that executor computation can never be thread-safe. Actually, I wonder why one would *ever* want to discard thread-safety. Maybe this is not about thread-safety in the graph computation, but something else? Can someone elaborate on this?
