Description:
------------
When using include_once with an abolute UNC file path, it is really
slow using php 5.2.5, php 5.2.4, and really fast using php 5.2.3

>From the script below :
PHP 5.2.5 :
first include_once : //NAS/nas/www/adodb5/adodb.inc.php
time (ms): 0.068962097167969
include_once count in 5 sec: 240   <<<<<<<<<<

PHP 5.2.3 :
first include_once : //NAS/nas/www/adodb5/adodb.inc.php
time (ms): 0.030542135238647
include_once count in 5 sec: 376054 <<<<<<<<<<

Thanks !
Lo.





Reproduce code:
---------------
<?php
// CASE MATTER !!!!
$absolutepath = '//NAS/nas/www/adodb5/adodb.inc.php';
$durationsec = 5.0;
///////////////////////////////////////////////////////////////////////////////
function sys_sinternal_microtime_float()
{
    list($usec, $sec) = explode(" ", microtime());
    return ((float)$usec + (float)$sec);
}
$t = sys_sinternal_microtime_float();
include_once('//NAS/nas/www/ea-land/private/prod/libs/adodb5/adodb.inc.php');
$t = sys_sinternal_microtime_float() - $t;
echo 'first include_once : '.$absolutepath.'<br>';
echo 'time (ms): '.$t.'<br>';

$cnt  = 0;
$t = sys_sinternal_microtime_float();
while(sys_sinternal_microtime_float() - $t < $durationsec)
{
        $cnt++;
        
include_once('//NAS/nas/www/ea-land/private/prod/libs/adodb5/adodb.inc.php');
}
echo 'include_once count in '.$durationsec.' sec: '.$cnt;
echo '<br>';
?>

Expected result:
----------------
"Include_once" should include_once should only include a file once
whitout doing extra processing as long as the file has an absolute path.

Actual result:
--------------
It's wotking well with php 5.2.3, but not anymore from php 5.2.4.
