I don't really understand this comment.
You can't get there after returning the COMMIT message. Once we have
finished waiting we set WaitingForSyncRep = false, before we return to
RecordTransactionCommit() and continue from there.
Anyway, this is code in the interrupt handler and only gets executed
when we receive SIGTERM for a fast shutdown.
