Batch callbacks for the Batch API tests.

Code

  // Initialize context with progress information.
  if (!isset($context['sandbox']['current'])) {

  }

  // Process by groups of 5 (arbitrary value).
  $limit = 5;
  for ($i = 0; $i < $limit && $context['sandbox']['count'] < $total; $i++) {
    // No-op, but ensure the batch take a couple iterations.
    // Batch needs time to run for the test, so sleep a bit.
    usleep($sleep);
    // Track execution, and store some result for post-processing in the
    // 'finished' callback.
