It was disabled for performance reasons. Bryan has updated the extension to improve its

changes, which, even by entirely dropping the data table and recreating it under the new
schema, will take time to apply. Once this schema change has been applied, it will be
possible to re-activate GlobalUsage.
Truncation is currently not running, right? Perhaps we could truncate
the table in a more or less database friendly way: while (
$dbw->query( 'DELETE FROM globalimagelinks LIMIT 5000' ) ) {
wfWaitForSlaves(5); }, so that the schema change can be easily
applied.
