is inited at the start of the DO action. I removed the Curl_transfer_keeper struct completely, and I had to move out a few struct members (that had to be set before DO or used after DONE) to the UrlState struct. The SingleRequest struct is accessed with SessionHandle->req. One of the biggest reasons for doing this was the bunch of duplicate struct members in HandleData and Curl_transfer_keeper since it was really messy to keep track of two variables with the same name and basically the same purpose!
