+      #

+      #   1) When the process that dies is the session leader of a session that

+      #      is attached to a terminal device, SIGHUP is sent to all processes

+      #      in the foreground process group of that terminal device.

+      #   2) When the death of a process causes a process group to become

+      #      orphaned, and one or more processes in the orphaned group are

+      #      stopped, then SIGHUP and SIGCONT are sent to all members of the

+      # POSIX.1 requires that every STOPPED process in an orphaned process

+      # group be sent a SIGHUP signal followed by a SIGCONT signal.  Since the

+      # second child is not STOPPED though, we can safely forego ignoring the

+         # it to acquire one by opening a terminal in the future (System V-

+    This module implements an xmlrpc server for BitBake.
+
+    Use this by deriving a class from BitBakeXMLRPCServer and then adding
+    methods which you want to "export" via XMLRPC. If the methods have the
+    prefix xmlrpc_, then registering those function will happen automatically,
+    if not, you need to call register_function.
+
+    Use register_idle_function() to add a function which the xmlrpc server
+    calls from within server_forever when no requests are pending. Make sure
+    that those functions are non-blocking or else you will introduce latency
+    in the server's main loop.
