Race condition
A race condition or race hazard is the behavior of an electronics, software, or other system where the system's substantive behavior is dependent on the sequence or timing of other uncontrollable events. It becomes a bug when one or more of the possible behaviors is undesirable.
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.
