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.
Race (human categorization)
A race is a grouping of humans based on shared physical or social qualities into categories generally viewed as distinct by society. First used to refer to speakers of a common language and then to denote national affiliations, by the 17th century the term "race" began to refer to physical (phenotypical) traits. Modern scholarship regards race as a social construct, that is, a symbolic identity created to establish some cultural meaning. While partially based on physical similarities within groups, race is not an inherent physical or biological quality.
