Just to be thorough, I created a php script:

<?php
echo "Hi";
?>

and replaced the 'hw.exe' with 'php hi.php' - I got the same problem
as originally reported.

I also tested 'php pipetest.php' from a telnet session, which (I
think) proves that it does not require a 'console'.

I'm getting to the point where I'm wondering if this is a Windows
limitation, but I do not have a unix-like box to test out this theory.
