[TYPO3-core] Caching framework and in-memory caching

[Peter Beernink]

Hi,

While debugging some performance issues during Extbase persistence, I 
also came across some calls to the caching framework.
When looking through the caching framework code it seemed that no 
in-memory caching is used during a single web request.
If I'm not mistaken this could limit the amount of requests needed to be 
made to the caching backend in quite some cases, and thus speed-up TYPO3 
in those situations.

Does anyone know if this is done intentionally?
