 I'd like more context to be available when the clean_post_cache hook is
 run.

 Scenario: I have a plugin caches the post_IDs of most post queries that go
 through WP_Query.  Invalidating that cache is done via the
 clean_post_cache hook, but requires a bunch of fragile hacks to prevent
 cache invalidation for things like comment inserts, which update the
 post's comment_count (which could, in theory, affect a WP_Query, but
 that's another story).

 Option 1: Add extra actions to provide context.  This is the simpler
 option.  Patch 1 does this for the above scenario.

 Option 2: Add an optional context parameter to clean_post_cache().  This
 is more general, but I can't think of anyplace else WordPress uses as
 similar approach.  Patch two.
