I have an urge to rename pending_response to pending_request.

pending_response sounds like a boolean state (waiting for response) rather than what it actually is.

My thinking was that the request has already happened (was sent), so we're indeed only still waiting for the response now. But maybe we use the word "pending" in a sligthly different meaning. I guess it can both mean something like "upcoming" (that's how I used it here), or "unanswered". Of course the server response is directly coupled to the request, so feel free to rename it if you like to.
