 * Overlaps codec resolution with the signed request it decodes, which every
 * read on a handle needs: the request is the same whatever the codec turns out
 * to be, so the two round trips are independent and there is no reason to pay
 * for them in series.
 *
 * The await order is the load-bearing part. The codec is awaited first so a
 * codec failure takes precedence over a read failure, and the no-op handler
 * attached to the request keeps an abandoned read from surfacing as an
 * unhandled rejection when the codec throws. The request is still awaited
 * afterwards, so its own error is never swallowed.
