Comment (by RogerTheriault):

 It seems the switch / restore code doesn't always call wp_cache_init() to
 recreate the $wp_object_cache, so the key can be incorrect in certain
 cases. Hooking to switch_blog and doing something like
 `$wp_object_cache->blog_prefix = $blog_id . ':';`
 might help, in addition to the original poster's recommendation.
