AutoIt and Python StdoutRead

[Hawkwing]

So I'm trying to have AutoIt interact with a compiled Python script using StdoutRead and StdinWrite, but it's a little weird.

This is the Python script that I've compiled to test.exe using py2exe

import time

while 1:
    try:
        print(raw_input())
    except:
        pass
    time.sleep(.05)

and this is the AutoIt code

#include<debug.au3>

HotKeySet('{end}','close')
HotKeySet('{home}','test')

$shell=Run(@MyDocumentsDir & '\Python\test.exe',@WorkingDir,@SW_SHOW,9)
_DebugSetup()
_DebugOut('test.exe')
Sleep(500)
While 1
    Sleep(50)
    $msg=StdoutRead($shell)
    If $msg<>'' Then
        _DebugOut($msg)
    EndIf
Wend

Func test()
    StdinWrite($shell,"this is a test"&@CRLF)
EndFunc

Func close()
    ProcessClose($shell)
    Exit
EndFunc

It looks to me like it should add 'this is a test' to the debug every time I press Home, but it doesn't. It's like it waits till test.exe closes to do anything. If you run it, hit Home a few times, and close the test.exe window, 'this is a test' pops up for however many times you hit Home, but I really don't get why it waits till you close it.

If you run test.exe by itself and type something in, it works as expected.

No one? It really has me confused
