inspectTemplates() let you flag all file compiled code the in the cache to be checked Once (Good) again, useful when you have Inspect templates set to Never (Best Performance).
The result is that only the changed files are re-compiled, all the others remain cached. Date checking occurs as the files are loaded, as does recompilation
Good for including in your application init/reload sections.
This is the smart version of pagePoolClear(), which just nukes your whole cache
