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.
Pre-existing condition
According to a Reason.com libertarian opinion blog by Peter Suderman, the 'Pledge to America' issued by the Republican Party in September 2010 stated, "Health care should be accessible for all, regardless of pre-existing conditions or past illnesses... We will make it illegal for an insurance company to deny coverage to someone with prior coverage on the basis of a pre-existing condition." In a March 3, 2010, address, President Barack Obama said that coverage denied to those with pre-existing conditions is a serious problem that would only grow worse without major reforms. In a September 2010 visit with Falls Church, Virginia, residents, Obama referred to a woman with an eye condition and a woman with non-Hodgkin's lymphoma as personal examples in the audience of those benefiting from changing pre-existing condition rules.
