Question, why remove the list at the begin of function void mleakdetect_dump(int fd)

[NanFeng009]

Just enter into mleakdetect_dump function, you empty the mleakdetect_stat list. the later that list still be used?

	TAILQ_FOREACH_SAFE(m, &mleakdetect_stat, next, mt) {
		TAILQ_REMOVE(&mleakdetect_stat, m, next);
		mleakdetect_free(m);
	}

The code preserves mleakdetect_stat after the mleakdetect_dump() is called. This intends that people can see the statistics with a debugger (maybe from core). And mleakdetect_dump() can be called multiple times. So the lines are to free mleakdetect_stat which was used when mleakdetect_dump() is called previously.
