Memory Leak in $STDOUT_CHILD

Hello everyone,

I've been experiencing a memory leak in one of my scripts, and I've traced it back to $STDOUT_CHILD.

After some research, I found some old topics (2007) about it, which indicates it's already solved, but for some reason, I still have a memory leak..

This is a (faster?) version of Valik's example, I think it meets the three conditions mentioned in the Help file, also, according to taskmgr.exe, the handles count is not continuously rising:

HotKeySet('{ESC}', 'Quit')

While 1
    $PID = Run('ping -t 0.0.0.0', '', @SW_HIDE, 2)
    Sleep(50)
    StdioClose($PID)
    StdoutRead($PID)
    ProcessClose($PID)
    Sleep(50)
    StdoutRead($PID)
    StdioClose($PID)
    Sleep(10)
WEnd

Func Quit()
    ProcessClose($PID)
    Exit
EndFunc

Am I missing something here?
