  1. Don't waste the last segment of each 4GB logical log file.

  2. Stamp HEAD as 9.3devel.

  3. Wake WALSender to reduce data loss at failover for async commit.

  4. Make the visibility map crash-safe.

Well, the question is for anywhere you might be thinking of using
this: why not just use List?  We do that in a lot of other places, and
there's not much reason to event something new unless there is a
problem with what we already have.  I assume this is related to
logical replication somehow, but it's not clear to me exactly what
problem you hit doing this in the obvious way.
