Comment:

 Next steps for this ticket (from core scrub):

 Sergey will "confirm the initial issue and verify that the patch does fix
 it as expected."

 Adding `needs-testing` to test for the performance gains:

 From Sergey:
 >Would be great to confirm the performance improvements, looks good to go
 otherwise

 Steps to test the performance improvements:
 >1. Use a persistent object cache (Redis or Memcached).
 >2. Have a site with a lot of pages.
 >3. Go to the the Pages screen (since it uses the get_pages() function
 being patched here) and measure the response time (TTFB, time to first
 byte).
 >4. Apply the patch and see if there's any improvement.
