 .. and throws an error in line wp-includes/class.snoopy.php on line
 894.[[BR]]
 There are several problems. It tries to allocate $this->maxlength bytes
 for a file to read. maxlength is set to 500.000 - as good as any other
 "guessed" value. What if the filesize is higher? Usually the filesize is
 lower. So I patched line 894 and replaced it with:

 {{{
 // $_data = fread($fp, $this->maxlength);
 $_data = '';
 while(!feof($fp)){
         $_data .= fread($fp, 10240);
 }
 }}}

 This might be slower. But we can ignore this, since it prevents us from
 running out of memory in low max_memory PHP environments. Less than or
 equal to 24MB.
 I have no idea what the other 23,5 MB were used for by WP, when I
 recognized this error?!
