> We routinely get reports like ARROW-11007 where there is suspicion of a memory leak (which may or may not be valid) — having an easy way (requiring no changes to application code) to toggle usage of the non-system memory allocator would help with determining whether the memory usage patterns are the result of the allocator being used.
