note 61692 added to ref.shmop

I wrote a php memcache back in 2003 as a sort of proof of
concept
it is use on a few machines for doing heavy page load
caching...
it works very well.
Following are some of the core functions I made 
<?           
###############################################
#### shared mem functions
/*
    for debugging these
        use `ipcs` to view current memory
        use `ipcrm -m ` to remove
        on some systems use `ipcclean` to clean up unused
memory if you
        don't want to do it by hand
*/

    function get_key($fsize, $file){
        if(!file_exists(TMPDIR.TMPPRE.$file)){
            touch(TMPDIR.TMPPRE.$file);
        }
        $shmkey = shmop_open(ftok(TMPDIR.TMPPRE.$file, 'R'),
"c", 0644, $fsize);
        if(!$shmkey) {
                return false;
        }else{
            return $shmkey;
        }//fi
    }
    function writemem($fdata, $shmkey){
        if(MEMCOMPRESS &&
function_exists('gzcompress')){
            $fdata = gzcompress($fdata, MEMCOMPRESSLVL);
        }
        $fsize = strlen($fdata);
        $shm_bytes_written = shmop_write($shmkey, $fdata,
0);
        updatestats($shm_bytes_written, "add");
        if($shm_bytes_written != $fsize) {
                return false;
        }else{
            return $shm_bytes_written;
        }//fi
    }
    function readmem($shmkey, $shm_size){
        $my_string = shmop_read($shmkey, 0, $shm_size);
        if(MEMCOMPRESS &&
function_exists('gzuncompress')){
            $my_string = gzuncompress($my_string);
        }
        if(!$my_string) {
                return false;
        }else{

        }//fi
    }
    function deletemem($shmkey){
        $size = shmop_size($shmkey);
        if($size > 0){ updatestats($size,
"del"); }
        if(!shmop_delete($shmkey)) {
            shmop_close($shmkey);
                return false;
        }else{
            shmop_close($shmkey);
            return true;
        }
    }
    function closemem($shmkey){
        if(!shmop_close($shmkey)) {
                return false;
        }else{
            return true;
        }
    }
    function iskey($size, $key){
        if($ret = get_key($size, $key)){
            return $ret;
        }else{
            return false;
