One of the things people seem to forget is that SQLite itself polls every millisecond or so to grab a lock. So yes, don't use this in a mobile device, or a server if you want to let the CPU enter a low power state. Otherwise, a single thread doing this in an otherwise idle server, doesn't seem that terrible. And if it's not idle, inotify won't help you (need to query what changed afterwards).
