If someone uses cp or scp to copy a WAL file from the pg_xlog
directory to an archive directory, there will be a window of time
where the file exists and is not complete. If you wait "a while"
(that being a duration which could be highly variable, depending on
the specifics of the environment and copy techniques used), the
missing part of the file will materialize.
