Comment:

 In [changeset:"46780" 46780]:
 {{{
 #!CommitTicketReference repository="" revision="46780"
 Options, Meta APIs: Avoid a race condition causing the first of two
 subsequent requests updating different options at the same time to lose
 changes.

 Every time an autoloaded option is updated or deleted, the `alloptions`
 cache is similarly updated. Due to the race condition, on any autoloaded
 option being updated, every other autoloaded option had its value set to
 the value at load time, causing a mismatch between the data in the
 persistent cache and the database.

 This change introduces a `$force_cache` parameter for
 `wp_load_alloptions()` to force an update of the local `alloptions` cache
 from the persistent cache when an option is added, updated, or deleted, to
 minimize the chance of affecting other options.
