- The schedule grid page is ridculously database-query heavy and hence
terribly lacking in perfmantitude.
- Caching can help with this, but the caching implemention at present
is not user-aware. If one user looks at the page, they'll get a
"YOU" in all the places they're chair and something else everywhere
else - and then everyone will see that for the next 600 seconds,
then YOU will become someone else
- to avoid this, remove the request.user-specific bit of the template
