Do you use cancellation? My current theory is maybe a missing need to call lockAndModify somewhere else. Auditing that...
Anyone have a test that can reproduce this?

Yes we are doing cancellation by calling Promise.completeWithCancel() but never lockAndModify directly. Nevertheless the crash happens inside lockAndModify. Do we need to call lockAndModify directly somewhere?
