No, it doesn't :-(

I used the following test code:

<code>
#! /usr/bin/python

from time import sleep
import sys,os,thread
from Tkinter import *

def one_th():
  sys.stderr.write('In the thread...\n')

if os.fork()==0:
  os.setsid()
  if os.fork()==0:
    sys.stdin=open('/dev/null','r')
    sys.stdout=open('/dev/null','w')

    thread.start_new_thread(one_th,())
    while True:
      sleep(60)
      try:
        rtk=Tk(screenName=':0.0')
      except:
        continue
      break
    Label(rtk,text='It works').grid()
    sys.stderr.write('Entering mainloop\n')
    rtk.mainloop()

  sys.exit(0)
</code>

I can see on root's console "In the thread...", and, after a while, "Entering mainloop", but
nothing shows up in user's screen.

Maybe it's simply impossible...
