> You can construct a RpcRetryingCallerFactory, but actually the conf is read 
> for each caller creation. Reading the conf is obviously expensive, and a 
> profiling session shows it. If we want to sent hundreds of thousands of 
> queries per second, we should not do that.
> RpcRetryingCallerFactory.newCaller is called for each get, for example.
> This is not a regression, we have something similar in 0.94.
> On the 0.96, we see the creation of: java.util.regex.Matcher: 15739712b after 
> a few thousand calls to "get".
