DRTVWR-209 Additional merge of viewer-development with SH-3316 drano-http code. Restore original deleteRequest/removeRequest implementation removing a small race.  Remove a short-lived additional timeout scheme on requests which really isn't appropriate as originally implemented as we can have very long-lived requests on big regions.
