That's what I meant. The "chaining" would be simple if the actions are stored in a sequential buffer: Just always add to the end, then work through them, waiting for one to complete before moving to the next.

But yeah, there's some complication if an operation fails. Or if written data is read again in the same boot (which shouldn't be much of a concern for elog)
