To quickly open a PyDoc browser, I want to be able to run the following:

python -m pydoc -g

This works fine on Python2.4, but fails on 2.5(.1), with following
traceback (tested on both WinXP and Solaris 8, same result):

Traceback (most recent call last):
  File "c:\python25\lib\runpy.py", line 95, in run_module
    filename, loader, alter_sys)
  File "c:\python25\lib\runpy.py", line 52, in _run_module_code
    mod_name, mod_fname, mod_loader)
  File "c:\python25\lib\runpy.py", line 32, in _run_code

  File "c:\python25\lib\pydoc.py", line 2191, in cli
    gui()

    gui = GUI(root)
  File "c:\python25\lib\pydoc.py", line 2052, in __init__
    import threading
ImportError: No module named threading


When running pydoc.py -g directly (i.e. without the -m) it works fine,
but this requires knowing the specific location of pydoc library file,
so is less helpful.
