Does this code work for you?
<?php
$handler=fopen("tmp.txt","w");
while(true) {
    echo "hey";
    fwrite($handler, "Hey\n");
}
?>

I wrote a test script just for this purpose:

<?php

echo "hey";
$handler=fopen("tmp.txt","w");
while(true) {
    fwrite($handler, "Hey\n");
}
?>

The echo _should_ be enough to display data for connections aborted. In
any case, i hit the "stop" button... and the script continues to run
taking 100% cpu time and the tmp.txt grows indefinitely. 

In case it is of any use, I am on windows 2003 using php through ISAPI.

Try with some other script which does NOT pipe anything anywhere..

yes, it does output data to the browser. My mistake, i forgot to
mention that after the data is piped to the program, the stdout is
piped into the browser.

Your page needs to output data to _browser_.

yes, my outputs data...

It pipes data through proc_open to a process in 8 or 16 kb chunks. It
should stop sending data to my process and close it when the connection
is aborted... I will try some tests with this function.
