Bug Description

Child process do
1. Set SIGHUP handler to hadle termination request
2. Set InactiveDestroy for parent's MySQL connection

If child signaled to terminate before 1 and 2 happened, parent connection will be shut down.

AutoInactiveDestroy seems not an option. Only precise/quantal/raring workers seems have it.
