Not sure if that is a fix that will work in all cases.

There is a potential timing problem with when the archiver is shutdown:
that may now be fixed in 8.4, see what you think.

Also if archiving is currently stalled, then files will not be
transferred, even if you switch xlogs. So this is at best a partial fix
to the problem and the need for a manual check of file contents
remains.
