 * What I want to say is that I wish to log all types of 404s, but I want the way
   how 404s are logged and stored in wordpress db to get improved.
 * Currently, in order to log 404 error, 404 module will retrieve the content of“
   seo_ultimate_module_404s” option, which is serialized list of all 404 hits, then
   it will unserialize it, add a new hit to that list, reserialize the list and 
   it will put serialized list back to “seo_ultimate_module_404s” option in wordpress
   DB.
 * In my case, the size of serialized array of 100 404s is ~400kb. When our site
   got scanned and got tons of 404 errors, our mysql servers almost crashed, because
   the memory was quickly taken away by ~400kb queries in binary log for replication.
 * It would be much nicer for servers to have a log of 1000 4kb queries instead 
   of 1000 400kb queries.
