Making HEAD requests to a page which has had output buffering activated just
results in the connection being closed with no response. This makes it
pretty unusable. Can anyone else reproduce this problem?
Two scripts:
nobuffer.php:
<? print "hello world!"; ?>
buffer.php:
<? ob_start(); print "hello buffered world!"; ob_end_flush(); ?>
nobuffer.php responds to the GET/HEAD requests fine.
buffer.php responds correctly to the GET, but not the HEAD.

I'll upgrade to RC4 in a bit and check if that makes a difference (not seen
the ChangeLogs between them yet)
(Platform is OpenBSD-2.8-stable). There is nothing in the Apache error log.
