Description:
------------
Function shmop_open increases memory used by Apache with about 4KB
every time it is invoked, and doesn't free it. It looks like memory
allocated for php_shmop struct is not freed.

Reproduce code:
---------------
<?
$shmid = shmop_open(0xff2, "c", 0644, 8);
shmop_close($shmid);
?>

Expected result:
----------------
Memory used by apache should be increased only once, when shared memory
segment is created. Refreshing the page should not increase used memory
or it must free it when script ends.

Actual result:
--------------
Every time the script is executed additional 4KB are added to the
memory used by Apache.
