Try these patches on 1.6.

Instead of adding to the existing posts query, I have 
update_category_cache() build $cache_category->fullpath which contains 
the full path of the category and its parents.  Then when a category is 
requested, it looks for the full path among the $cache_category array. 
If it can't find it, it looks for the last directory in the path.

These patches reduce the potential number of queries used by 1.

Please *test*.
