Optimize app compaction system reduce page faults
This patch allows for amortizing the memory churn in compaction
over time by reusing the vector and its vmas as well as sending
a preassigned buffer to fill maps. Effectively, after a compaction
run we usually see no new allocations which also reduces the page
fault cost and the allocation cost.
