This 'absolutely not' a read of uninitialized memory is '100% not' the cause of our non-deterministic behavior on the Intel NUC. If there was a such an error, it would show up on all FifoCi backends equally. This is 'probably' unrelated to the fact that the Intel NUC is the only fifoci runner not running under virtualization.
