I thought about this. If this is the case, why do we closeAllDatabases when ProcessWillSuspendImminently? We could just let the running transaction be finished or interrupted?

Also, if this causes big power regression, shouldn't we find all the places that could have database connection open for a long time but not actually doing anything and close them? I was told we are not supposed to keep open database connection when there is no database activity.
