BLOCKING option [database]

Description 

When BLOCKING is ON, any transaction attempting to obtain a lock that conflicts with an existing lock waits for BLOCKING_TIMEOUT milliseconds for the conflicting lock to be released. If the lock is not released within BLOCKING_TIMEOUT milliseconds, then an error is returned for the waiting transaction.

Setting this option to 0 forces all transactions attempting to obtain a lock to wait until all conflicting transactions release their locks.
