It is not a complete solution, but it does help to a degree, if the next attack mirrors the previous one.  Client.reconnect commands were included in the stratum mining protocol for a reason. The 'patch' to which you are referring is built into the latest versions of kalroth cgminer and veox sgminer.  Just check their docs for use of no-client-reconnect option.  But be forewarned, some pools might legitimately utilize the command, either now or in the future, so to enable it could break certain functionality.  But poolwaffle has stated that he does not ever use it, so safe to use here.
