I disagree. There is an extremely small chance of having a race
condition, as users can only update their own data, no one elses.
Unless a user is logged on twice, a race condition should never occur.
Even if they did log in twice, they'd have a very narrow window within
which to create the race condition. If they did, they would have to
deal with having duplicated books. Hehe.
Many thanks.
Daz.
