* they now can take a *doOptions uniformly to control timeout: - nil or absence uses the defaults - there's a predefined doNoTimeoutAndRetry to get no timeout * there's a simple and a full parameter only variant of doSync and doAsync * use rawWithTimeout in the places that were using raw but setting a timeout via context themselves
