Race condition
Race conditions arise in software when an application depends on the sequence or timing of processes or threads for it to operate properly. As with electronics, there are critical race conditions that result in invalid execution and bugs. Critical race conditions often happen when the processes or threads depend on some shared state. Operations upon shared states are critical sections that must be mutually exclusive. Failure to obey this rule opens up the possibility of corrupting the shared state.
Lothrop Stoddard
Stoddard argued that race and heredity were the guiding factors of history and civilization and that the elimination or absorption of the "white" race by "colored" races would result in the destruction of Western civilization. Like Madison Grant in his "The Passing of the Great Race", Stoddard divided the white race into three main divisions: Nordic, Alpine, and Mediterranean. He considered all three to be of good stock and far above the quality of the colored races but argued that the Nordic was the greatest of the three and needed to be preserved by way of eugenics. He considered most Jews to be racially "Asiatic" and argued for restricting Jewish immigration because he considered them a threat to Nordic racial purity in the US. He warned that US was being "invaded by hordes of immigrant Alpines and Mediterraneans, not to mention Asiatic elements like Levantines and Jews."
