I Do NOT recommend doing this. (long experience with multi-file Desktop database: Paradox DOS. A sure-fire way to damage things: Cached writes)
Caching can get things horribly out of sync.
Calibre is transactional. It writes into the DB, and it writes book files (not sure which order). If the queue has 2 operations on a book before the cache flushes those items to disk
