Comment:

 Mmm, I love posts that have more red than green.

 This eliminates some seriously redundant code, and reduces the number of
 queries made fetching post meta.

 I found another issue that is fixed in my patch: subsequent loops would
 destroy earlier postmeta cache entries.  So if the loops had entries in
 common, the meta for those common entries was being fetched, destroyed,
 and fetched again.  Bad.

 Please review and test.
