# SQLite does not implement SELECT FOR UPDATE which is normally used to place
# an exclusive lock over rows to prevent the same address from being

# over the entire database and we perform a row update for any IP that we
# allocate, requiring an exclusive lock. Taking the exclusive lock from the
# start of the transaction (even if it were not required to guard the SELECT)
# is actually quicker than if we deferred it causing SQLite to "upgrade" the
# automatic shared lock for the transaction to an exclusive lock for the
# subsequent UPDATE.
