I can fix this problem locally in tomography by explicitly marginalizing if the size of the returned result is not the same as the number of clbits, but this is...

The cause for problems here is `exp_data.save()` because `save` only saves the children that were already added to `exp_data`, and adding new children is done concurrently. Doing `exp_data.block_for_results().save()` fixes it;...

It should be possible to cancel the JKU process, but it will require some code changes and careful testing. Let's see if we decide we want local simulators to implement...
