I meant this as a way to convey that this function is 'private', and is not a 
test case that is exposed. Suggestions for alternatives welcome!

I think the keys are always there, unless they are removed from 
ClientRequestState::ClientRequestState() and ClientRequestState::Done(). We'd 
be able to catch the regression then. Since clients expect to see these, I 
think it's good to assume so in the test case as well.
