What is a race condition?
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.
The Race Question
The first version did not reject the idea of race biology, a biological basis to racial categories. It defined the concept of race in terms of a population defined by certain anatomical and physiological characteristics diverging from other populations; it gives as examples the Caucasian race, Mongoloid and Negroid races.
