> There is a check in the client to be sure that we don't use a timeout of zero (i.e. infinite).
This includes setting the minimal time out for a rpc timeout to 2 seconds. However, it makes
sense for some calls (typically gets going to the cache) to have much lower timeouts. So it's
better to do the check vs. zero but with a minimal timeout of 1. 
> I fixed a typo & a wrong comment in this patch as well. I don't understand this code:
> {code}
>       // t could be a RemoteException so go around again.
>       translateException(t); // We don't use the result?
> {code}
> but may be it's good.
