To state that a single solution is undesirable without the need of supplying an alternative just isn't successful. I'm usually searching for means to further improve and when there is an alternate I'll gladly investigate it and weigh the professional's and cons.
So race condition in software program business usually means "two threads"/"two processes" racing one another to "impact some shared condition", and the final results of the shared state will rely upon some subtle timing variation, which may be because of some distinct thread/procedure launching buy, thread/procedure scheduling, etcetera.
