This commit started out investigating a `concurrent map read write` issue, ending by replacing the map with a struct. This is easier to reason about, and it's more effective: ``` name old time/op new time/op delta SiteNew/Regular_Deep_content_tree-16 71.5ms ± 3% 69.4ms ± 5% ~ (p=0.200 n=4+4) name old alloc/op new alloc/op delta SiteNew/Regular_Deep_content_tree-16 29.7MB ± 0% 27.9MB ± 0% -5.82% (p=0.029 n=4+4) name old allocs/op new allocs/op delta SiteNew/Regular_Deep_content_tree-16 313k ± 0% 303k ± 0% -3.35% (p=0.029 n=4+4) ``` See #8749
