We have some challenges in ensuring the pseudo database is flushed to disk in things like docker containers since the processes can be killed with no warning at container termination. Rightly or wrongly, we need to handle this better. There is no current way to flush the DB but there is a shutdoen request
typo shutdoen/shutdown
mechanism. Whilst we can't force a shutdown from bitbake due to the multiple connected clients and the existing 3s shutdown isn't enough, we can take the hint to flush the DB at this time.
