We are having problems using shm functions.
Taking a look at sysvshm.c, it seems that shm_remove
take as argument **key** and not **shm_identifier** as
documented (even on the snapshot documentation).

Some tests show the same results. Here follows the code
to test it:

<?php

$key = 5;
$shm_identifier = shm_attach($key);
shm_remove($shm_identifier);

$key = 6;
$shm_identifier = shm_attach($key);
shm_remove($shm_identifier);

$key = 7;
$shm_identifier = shm_attach($key);
shm_remove($shm_identifier);

echo "Many warnings appeared above<br>";
shm_remove(5);
shm_remove(6);
shm_remove(7);
echo "No warnings now<br>";

?>
