Comment(by huhabla):

 I have implementation GRASS messenger interface prototype. The file is
 attached in the ticket. It uses the Python multiprocessing interface. The
 IPC is handled via pipes. Here a usage example:

 {{{
     msgr = Messenger()
     msgr.message("message")
     msgr.verbose("verbose message")
     msgr.important("important message")
     msgr.test_fatal_error()
     msgr.percent(1, 1, 1)
     msgr.debug(0, "debug 0")
     msgr.warning("Ohh")
     msgr.debug(1, "debug 1")
     msgr.error("Ohh no")
     msgr.stop()
     # This should result in:
     """
     message
     important message
     ERROR: this is a fatal error
     WARNING: Needed to restart the messenger server
      100%
     D0/0: debug 0
     WARNING: Ohh
     ERROR: Ohh no
     """
     # Test of the percentage creation
     msgr = Messenger()
     num = 100000
     for i in range(num):
         msgr.percent(i, num, 10)
     msgr.stop()
 }}}

 What are you thinking, any improvement suggestions, enhancement requests?
 :)

 I would like to put the attached file {{{__init__.py}}} into a new pygrass
 directory "lib/python/pygrass/messenger", if there are no objections
 against it.
