Unlike prof_sample which is supported only with profiling mode active, prof_threshold is intended to be an always-supported allocation callback with much less overhead. The usage of the threshold allows performance critical callers to change program execution based on the callback: e.g. drop caches when memory becomes high or to predict the program is about to OOM ahead of time using peak memory watermarks.
