Lighttpd

Hello,

I have a problem with Lighttpd 1.4.45 on Debian testing.
BUT, I think this is very important, I haven't any problem with Lighttpd 1.4.35 on Debian testing.

With Lighttpd 1.4.45, the following PHP script use output buffering.
=> the result is sent to the browser in one time :(

With Lighttpd 1.4.35, the following PHP script doesn't use output buffering.
=> the result is sent to the browser in 5 times :)

<?php

header('Content-Encoding: chunked');
header('Content-Type: text/plain; charset=utf-8');
header('Cache-Control: no-cache, must-revalidate');
ini_set('output_buffering', false);
ini_set('implicit_flush', true);
ob_implicit_flush(true);
for ($i = 0; $i < ob_get_level(); $i++)
    ob_end_clean();

echo "a\n";
flush();
sleep(1);

echo "b\n";
flush();
sleep(1);

echo "c\n";
flush();
sleep(1);

echo "d\n";
flush();
sleep(1);

echo "e\n";
flush();

Why? I don't understand.
