-Subject: [PATCH] Create a thread to reap death process
-
-ForkingWSGIServer use `SocketServer.ForkingMixIn` to implement a
-multiprocess server.  This class provides a workflow that collect
-death process (process in Zombie status) before the
-`process_request`.  This means that this process itself will be
-in Zombie status at the end of the request, that will be eventually
-collected during the next `process_request`.
-
-To minimize transient Zombie process, `ForkingWSGIServer` is
-creating a daemon thread (via `threading.Timer`) to call the
-collector every (by default) 5 seconds.
-
-Fixes #810
