Comment(by annakrat):

 I just tried this python
 [http://code.activestate.com/recipes/278731-creating-a-daemon-the-python-
 way/ recipe] and it worked for me, the processes are terminated. I tried
 to find the difference and it seems that just this line is enough (in the
 GuiModuleMain function):

 {{{
 --- core/utils.py       (revision 58561)
 +++ core/utils.py       (working copy)
 @@ -1064,7 +1064,8 @@
          child_pid = os.fork()
          if child_pid == 0:
              mainfn()
 -        os._exit(0)
 +        else:
 +            os._exit(0)
      else:
          mainfn()

 }}}

 Can I apply it safely or can it cause some other troubles?
