How does the db library work??

FYI, if you run into a more complicated case where you have to ensure that your database is always in a consistent state even across different threads, I highly advise you to read up on transactions. Everything enclosed within a transaction is an all-or-nothing prospect. If you're dealing with financial databases or other business critical systems, this is most certainly the way to go.
