This issue has come up before. The choices seem to be retry forever or
retry some number of times and then give up unless someone can see a
better "policy". 

The rety strategy might also depend on the status code returned from the
SA although the errors may not be sufficiently rich for different client
behavior but it could be based on the join type and the status code.
Some errors to certain joins might indicate that retries might never
succeed no matter how many retries are attempted.
