 `get_option()` (among other functions) calls `wp_load_alloptions()`:
 https://core.trac.wordpress.org/browser/tags/4.4/src/wp-
 includes/option.php#L27

 `wp_load_alloptions()` is never cached on multisite:
 https://core.trac.wordpress.org/browser/tags/4.4/src/wp-
 includes/option.php#L174

 This combines to result in many dozens unnecessary calls to the database
 on multisite installs when using options, for example 1 database query per
 `get_avatar()`. options should be cached, or at the very least be
 filterable such that I can cache them myself.
