TCEmain clears cache inefficiently
In TCEmain::clear_cache() the cache for certain page IDs gets cleared through a foreach loop calling flushByTag. Instead of the many calls to flushByTag() single calls to flushByTags() should be made.

The flushByTags() method is a v4 method which is not implemented in FLOW3.
I have a bug in mind that the different backends react differently on flushByTags(): Some of them clear an entry if it is tagged with one of the tags, some others clear an entry if it is tagged with any of the tags. This needs to be sorted out and fixed before the above issue is tackled.
