 명령 출력에 대략적인 총 바이트 수가 표시되는 것은 설계에 따른 것입니다. 

여기에는 두 가지 이유가 있습니다.

각 프래그먼트 크기에 대해 모든 프래그먼트의 합계를 구해야 하는 경우 단일 프래그먼트 크
기에 대한 할당이 너무 많고 정확한 값을 얻으려면 수천 개의 청크를 확인해야 하기 때문에 성
능이 저하될 수 있습니다.

각 휴지통 크기의 경우 이중 링크된 할당 목록을 확인해야 하며 많은 할당이 있을 수 있습니다
. 이 경우 연장된 기간 동안 CPU를 사용할 수 없으므로 할당을 주기적으로 일시 중단해야 합니
다. 할당을 다시 시작한 후에는 다른 프로세스에 메모리가 할당되거나 할당 취소되고 메모리 
상태가 변경될 수 있습니다. 따라서 total bytes 열에 실제 값 대신 근사값이 제공됩니다.
