Subject Re: CMS does not correctly support prefetchSize=0

Its possible we don't support it correctly, I don't know as we've ever
really tested that.  

I'd suggest you write a Jira Issue describing what you are seeing as
well as some sample code that reproduces the problem so that when one of
us has time we can look into it.
