Lifetime이 같은 pages를 fixed-size contiguous regions에 함께 배치해 process kill 시 region 전체가 contiguous free space가 되게 하는 proactive anti-fragmentation 방식이다.

Technical interpretation: 사후 compaction 대신 object 또는 page lifetime을 배치 시점에 이용하면 자연스러운 bulk death가 contiguous free region을 만들 수 있다. Controlling Physical Memory Fragmentation in Mobile Systems Nexus 10 Android-kernel prototype에서 fragmentation, I/O-buffer allocation time, CPU usage, energy consumption을 줄였다고 보고하지만 공개 초록에는 수치가 없다. Process spawn과 exit로 fragmented된 모바일 물리 메모리에서 large contiguous I/O buffer allocation 비용을 예방할 수 있는가? lab 사후 compaction 대신 object 또는 page lifetime을 배치 시점에 이용하면 자연스러운 bulk death가 contiguous free region을 만들 수 있다.
