Comment (by kurtpayne):
The [[attachment:map_meta_cap.patch]] patch makes the following
assumptions:
1. calls to map_meta_cap are deterministic - a user is either capable or
incapable of doing something in a given invocation
2. if !#1 isn't true, then the call to `map_meta_cap` can use
`$cache=false`
3. the cache should only be valid for the life of the process; using the
`wp_cache_*` methods for persistent caching would be inefficient and
unnecessary
In xdebug profiles, this has decreased run time of the "all posts" page by
12%. Without xdebug (running faster without the profiling overhead), run
time (measured with Chrome's net panel) has decreased by about 8%.
