> The template cache is currently just a map per segment. This is problematic in various
ways: 
> * A segment needs to be in memory and probably loaded first only to read something from
the cache. 
> * No monitoring, instrumentation of the cache
> * No control over memory consumption 
> We should there for come up with a proper template cache implementation in the same way
we have done for strings ({{StringCache}}) in OAK-3007. Analogously that cache should be owned
by the {{CachingSegmentReader}}.
