Earlier quoted context omitted.
Nitpick, I assume by "race condition" you mean "used lots of CPU". This is a common colloquial conflation, but race conditions [1] (which are not generally identifiable without aid of a debugger and the application's source code) and high CPU usage are unrelated concepts. [1] https://en.wikipedia.org/wiki/Race_condition
That's not a nitpick. These are entirely different things and calling high CPU usage a "race condition" is really confusing and misleading. Do people actually do that? Where did that come from?
Maybe because it makes your machine's fans sound like a race car?
Honestly this is the first I've heard of this usage as well.
