Description:
------------
The documentation of fstat (http://www.php.net/manual/en/function.fstat.php) shows a note : "Note: The results of this function are cached. See clearstatcache() for more details.".

However clearstatcache's documentation (http://www.php.net/manual/en/function.clearstatcache.php) does not list fstat in the list of affected functions.

After a test with PHP 4.3.10 (Win32), it seems that fstat is *not* cached.

Reproduce code:
---------------
<?php
touch('TEST.BIN'); // make sure this file exists
$fp=fopen('TEST.BIN','r+b');
ftruncate($fp,0);

$stat=fstat($fp);
echo $stat['size']."\n";
fwrite($fp,"TEST");
$stat=fstat($fp);
echo $stat['size']."\n";
fclose($fp);
unlink('TEST.BIN');


Expected result:
----------------
If clearstatcache documentation was correct we should receive :
0
0

Actual result:
--------------
Actually the code shows :
0
4

fstat() documentation is not correct : the function is not cached (at least for normal file streams)
