always use a template method cache even if the template cache flag is set to false. This flag is only used to make dynamic updates to the template files, to not dynamic updates to the rewrite methods (which is not possible without recompiling). low memory usage is guaranteed by the usage of soft references which are dropped before an OOM is thrown
