This is used for two memory reporting improvements. - It's used to distinguish "explicit" memory reports from others. This mirrors the same categorization that is used in Firefox, and gives a single tree that's the best place to look. It replaces the "pages" tree which was always intended to be a temporary stand-in for "explicit". - It's used to computed "heap-unclassified" values for both the jemalloc and system heaps, both of which are placed into the "explicit" tree. Example output: ``` | 114.99 MiB -- explicit | 52.34 MiB -- jemalloc-heap-unclassified | 46.14 MiB -- system-heap-unclassified | 14.95 MiB -- url(file:///home/njn/moz/servo2/../servo-static-suite/wikipe dia/Guardians%20of%20the%20Galaxy%20(film)%20-%20Wikipedia,%20the%20free%20encyc lopedia.html) | 7.32 MiB -- js | 3.07 MiB -- malloc-heap | 3.00 MiB -- gc-heap | 2.49 MiB -- used | 0.34 MiB -- decommitted | 0.09 MiB -- unused | 0.09 MiB -- admin | 1.25 MiB -- non-heap | 1.36 MiB -- layout-worker-3-local-context | 1.34 MiB -- layout-worker-0-local-context | 1.24 MiB -- layout-worker-1-local-context | 1.24 MiB -- layout-worker-4-local-context | 1.16 MiB -- layout-worker-2-local-context | 0.89 MiB -- layout-worker-5-local-context | 0.38 MiB -- layout-task | 0.31 MiB -- display-list | 0.07 MiB -- local-context | 1.56 MiB -- compositor-task | 0.78 MiB -- surface-map | 0.78 MiB -- layer-tree ``` The heap-unclassified values dominate the "explicit" tree because reporter coverage is still quite poor.
