Comment (by jeremyfelt):

 [attachment:25158.2.diff] makes use of a local `$current_site =
 get_current_site();` when it makes sense rather than calling
 `get_current_site()` each time. There are a couple places where I've left
 multiple function calls in place as there are situations where only one of
 them will be called depending on logic.

 Also removed an unused `$wpdb` global in `ms_site_check()`
