note 18281 added to ref.shmop

You can write to an existing shared memory segmenet if you have permissions to do so. In the old version, 'a' option was inproperly documented & coded, it reality it opened the segment for read & write. In the current CVS, I have fixed this problem. -- http://www.php.net/manual/en/ref.shmop.php http://master.php.net/manage/user-notes.php?action=edit+18281 http://master.php.net/manage/user-notes.php?action=delete+18281 http://master.php.net/manage/user-notes.php?action=reject+18281
