 Replying to [comment:4 convissor]:
 > The new, efficient code for switching between blogs is an excellent
 improvement.  Thanks.

 {{{wp_cache_reset()}}} / {{{WP_Object_Cache::reset()}}} and why the
 deprecation message instructs people to use
 > {{{wp_cache_switch_to_blog()}}} / {{{switch_to_blog()}}}?  The
 {{{reset()}}} and {{{switch_to_blog()}}} methods serve two separate
 purposes.  (Though some people may have used them in conjunction.)

 wp_cache_reset() was only ever implemented by the default, built-in cache.
 The other backends did not implement it. Now that we have switch_to_blog()
 it is even more useless since core never calls it.
