A relevant paragraph copied from the original commit history: The idea is that we store all strings somewhere managed, and then the hashmap only needs pointers to those strings. For storing strings, I created a `Textbook` structure, which consists of one or more 50 KB "pages" (allocated as needed) on which you can simply write strings in both languages back-to-back with `textbook_store(textbook, text)` and get pointers to each of them. (I was originally going to just use one big buffer and realloc to double the size when filled up, but then the hashmap would be full of dangling pointers...) When needed, like when switching to a different language, an entire textbook can be freed at once. This commit is part of rewritten history of the localization branch.
