/// Each page is a fixed size.
/// Uses io_uring to do the writes async. Reads are synchronous
///
/// TODO: deleted pages are not destroyed, they are just left on disk, which means if the same
///   page id is re-used, the old data could be read.
/// TODO: right now page storage is page-per-file which is maybe not the most efficient.
/// TODO: verify the fsync chained to writes via io_uring is actually working, and that
///   the durability guarantees are, at least approximately, correct.
/// TODO: we'll need reads once eviction/paging is implemented.
