Fix Version/s: None
[Affected version: at least 5.5.28a-MariaDB-log]
When a user performs queries handled by query-cache theses are not taken into account by USER_STATISTICS (and probably neither by HOST_STATISTICS).
They should properly increment COMMAND_SELECT, SENT_ROWS and when appropriate EMPTY_QUERIES.
Without updating those a user that performs the same SELECT over and over, each time hitting query cache will appear as performing no queries, just burning CPU time and exchanging bytes.
