Detailed Description

A short fixed list of callbacks, run in the order they were added.

The stores hang their periodic work on one of these, and the transport keeps another for the work that waits until a whole inbound message is handled. Each list lives in the file that owns it, with room set by how many callers there can be, so nothing here allocates.
