Regardless, if you yourself happen to know any sources that weren't covered in other comments, please share them.
I remember learning about race conditions in college, and they were always mentioned in the context of bugs - that's why I took Wikipedia itself for granted, as its definition fit my current understanding of the word.
It seems to be a case of popular usage of the word differing from the original. It also raises a question of whether or not the original intended meaning is the authority, if the majority of programmers use it in a different way. Who should, in general, be the authority on the meaning of a word? But that's more of a philosophical question, I suppose.
