By passing the Config instantiation through the Injector and service configuration we're unnecessarily calling Config::inst()->get() on a config system which doesn't yet exist.
More specifically it calls Config::inst()->get('Config', 'dependencies') here: 4ae0d90c55/control/injector/Injector.php (L660) which in turn calls Config::inst()->get('Config', 'extensions').
This jumps through hoops trying to find the cached config for this class using the current Config_LRU class. When it doesn't find it, it then tries to look through the manifests which don't get created or brought from cache until later on in Core.php. Eventually this returns null for both Config::inst()->get() calls.
I ran a quick performance test before and after on an ec2 t2.micro box using siege (concurrency 5, 10 repetitions) and saved 400ms on average response times on a default installation - it would be awesome if somebody could confirm this is actually the case?
Returns the table name for a field in a class hierarchy.
This issue raised itself with GridFieldSortableHeader not supporting sorting on fields from parent class fields.
Provides an interface for classes to implement their own flush()
functionality. This function gets called early in a request on
all implementations of Flushable when flush=1|all is requested in the
URL.
This fix came out of an issue where Requirements combined files were not
being cleaned up after dev/build?flush=1, due to the fact that flush
would only occur when you called it while on a page that used those
combined files, but not in any other contexts. This will now call flush
on any implementors of Flushable regardless of the context of where
flush was called.
Specific case: LeftAndMain::$session_keepalive_ping = true cannot be
set to false in config.yml for some cases because the value is ignored
when merge_array_low_into_high() is processing the config arrays.

Injector::nest and Injector::unnest are introduced to better support sandboxing of testings.
Injector and Config ::nest and ::unnest support chaining

Bots often have the habit of trying a next page, even if there isn't one.
Thus, using CurrentPage < TotalPages, prevents from unwanted next-links being shown.
Fixes issue of templates not being found when a Page's main/Layout templates are split between the project and theme folders. Adds more expansive testing for template loading.
