Re: problem with reload(sys) (doing reload on the sys module)

Looks like a bug (probably in IDLE): when I start IDLE from the command
line, it pops up its interaction window and here is what it says about
stdout:

IDLE 1.1.2[color=blue][color=green][color=darkred]
>>> import sys
>>> sys.stdout[/color][/color][/color]
<idlelib.rpc.RP CProxy instance at 0xb76a490c>

Then I try the reload and I get no output in the interaction
window:
[color=blue][color=green][color=darkred]
>>> reload(sys)
>>> sys.stdout
>>>[/color][/color][/color]

After the reload, stdout has been changed to the terminal from which
IDLE got started, so I see the messages there:

<module 'sys' (built-in)>
<open file '<stdout>', mode 'w' at 0xb7b67068>

As you can see, stdout has been redefined (back to the way it would be if
you started Python from the command line, with no IDLE involved).

hi nick,

have you found any solutions to this problem.
maybe sys module does not need to be reloaded.
may Tim peters and the rest can help us on this
