Comment:

 Re-opening this for some further discussion:
  * _blog_option() was never good, but these changes do highlight some
 problems because a switch_to_blog() clears the local cache. If you don't
 have a persistent backend, this means a single get_blog_option() wipes out
 most of your cache for the rest of the page.
  * We should remove all usage of _blog_option() in core.
  * We should deprecate _blog_option() in favor of "switch_to_blog(),
 get_option()" to ensure that people actually do realize that
 get_blog_option() is no less expensive.
  * We should improve our default caching backend to have a way to init it
 for a single blog, without losing the existing local cache.
