See https://discourse.phabricator-community.org/t/unhandled-exception-when-accessing-badges/3010/.

The "Badges" tab on user profiles may overheat explosively.

This specifically appears to be arising from this unusual query:

$badges = id(new PhabricatorBadgesQuery())
  ->setViewer($viewer)
  ->withStatuses(array(
    PhabricatorBadgesBadge::STATUS_ACTIVE,
  ))
  ->requireCapabilities(
    array(
      PhabricatorPolicyCapability::CAN_VIEW,
      PhabricatorPolicyCapability::CAN_EDIT,
    ))
  ->setLimit(1)
  ->execute();

We're using this to implement a behavior: if the user can't award any badges, don't show the "Award Badge" button.

This behavior is not consistent with how the rest of the UI works and can not be queried efficiently in the general case, so I'm just going to drop it.
