Title: When writing to ijod, use just one connection for the whole batch

Should save pool crushing during the pump/writing stage, and save a ton of network overhead too.

The Friends stuff still (on new friends) writes individually yet to that's a TODO, but all other data (most of our work) will benefit from this.
