-// used by both.
-//
-// In order to keep the client simple while allowing it to be thread
-// safe and async signal safe, the main broker socket is used only for
-// requests; responses arrive on a per-request socketpair sent with
-// the request. (This technique is also used by Chromium and Breakpad.)
