I do not want my applications to get an error, only a delay.  Without this it is not possible to recover gracefully from a server/network failure.

http://www.gluster.org/docs/index.php/Translators_v1.4#client says:
"# option transport-timeout 30            # seconds to wait for a response
                                         # from server for each request"

Setting that to 604800 should give you a week to fix the server. ;-)
I hope it will try to reconnect sometimes to see if the server is up again.
