 On some servers, including Wordpress installs hosted by Green Geeks (PHP
 5.2.9: see http://www.greengeeks.com/phpinfo.php), apache_mod_loaded will
 actually fail in such a way that pages will cease to render, which affects
 both the Permalinks page and the Media uploader if running on a Mac.
 (There are possibly other side effects that I am unaware of, but these are
 the two major side effects I've seen.)

 The problem appears to be localized around the use of ob_get_clean in the
 definition of apache_mod_loaded in the branch that has to parse phpinfo.
 Replacing ob_get_clean with ob_get_contents and ob_end_clean fixes the
 problem entirely on the site I'm currently working on.  I realize
 ob_get_clean is supposed to be equivalent to ob_get_contents +
 ob_end_clean, but in this case at least, it seems to be significant.  I
 don't know why this is the case, but since it seems to be fixed and I have
 seen a number of support forum topics regarding the Media upload form with
 a Mac that suggested just commenting out the code that uses
 apache_mod_loaded to test for Mac + mod_security, I strongly suggest
 making this minor edit for the good of all users.
