MacOS counts MADV_FREE pages as part of a process's memory in activity monitor, even if they're not currently used and could be reclaimed. To avoid this MacOS also provides MADV_FREE_REUSEABLE which will cause them to not be counted (but otherwise behave the same).
We previously made this change for the JS GC in Bug 1567366.
