Comment:

 > In very rare circumstances some options may not be in DB but in cache.

 Knowing under what circumstances this would occur is really the only good
 way to fix this.

 I understand the desire to wp_cache_delete() in these situations, but I am
 not sure about the desire to re-add. There is a concern that cache is
 stale, should just work to clear the cache and let it balance itself out
 later.

 This is lacking unit tests to demonstrate the bug and/or fix, so I'm
 moving it to future release pending additional feedback.
