The startup process runs at 100% CPU, with no output from strace.  There are no queries running on the secondary, so it's not a delay for queries.  The WAL receiver continues to operate normally, and we can see sent_location / write_location / flush_location continue to move ahead in parallel, with replay_location stuck in that WAL segment.

Attach to startup process with gdb, and get a stack trace?
