* PPTC vs. giant ExeFS. * InternalVersion = 2168 * Add new heuristic algorithm for calculating the number of threads for parallel translations that also takes into account the user's free physical memory and not just the number of CPU cores. * Nit. * Add an outer Header structure and add the hashes for both this new structure and the existing "inner" Header structure. * InternalVersion = 2169
