Comment 2 for bug 1020238

There was a discussion about this on the dev mailing list and I was curious about the final resolution. This change breaks Tempest and I am about to change it to pass the no_cache argument. But then it won't work with the older client. I am not sure what kind of stability we are trying to provide in the client projects. It also doesn't seem friendly for a python API to require reading from stdin in order to continue. Perhaps only the cli part should do this?
