Description:
------------
For some reason not clear to me, using iterator_count with the iterator interface 
of SplFileObject (as well with SplTempFileObject) results in an endless running 
script.

Test script:
---------------
<?php
$test = new SplFileObject("data://text/plain,1\n2");
$test->setFlags(SplFileObject::DROP_NEW_LINE);
echo "Values: [", implode(', ', iterator_to_array($test)),
     "]\nCount: ", iterator_count($test), "\n";
?>

-- OR --

<?php
$test = new SplTempFileObject();
$test->setFlags(SplTempFileObject::DROP_NEW_LINE);
$test->fwrite("1\n2");
echo "Values: [", implode(', ', iterator_to_array($test)),
     "]\nCount: ", iterator_count($test), "\n";
?>

Expected result:
----------------
Values: [1, 2]
Count: 2

Actual result:
--------------
Values: [1, 2]
Count:
