The behavior is a design flaw of the MySQL database, which is only OK for 
read-only operations but may totally break when changing records (esp. in a 
transaction). Therefore, they turned it off by default now.

PDNS can't do anything besides enforcing the flag to be turned off because it 
don't get notified if an auto-reconnect happens.
