+  # Used to represent the number of +active+ and +queued+ sockets for
+  # a single listen socket across all threads and processes on a
+  # machine.
+  #
+  # For TCP listeners, only sockets in the TCP_ESTABLISHED state are
+  # accounted for.  For Unix domain listeners, only CONNECTING and
+  # CONNECTED Unix domain sockets are accounted for.
+  #
+  # +active+ connections is the number of accept()-ed but not-yet-closed
+  # sockets in all threads/processes sharing the given listener.
+  #
+  # +queued+ connections is the number of un-accept()-ed sockets in the
+  # queue of a given listen socket.

+  # These stats are currently only available under Linux
