I'm unsure of the capabilities of *new* RPG programs to take advantage of
multi-threading.  Multi-threaded apps have ops such as thread_create(),
thread_lock(), thread_destroy(), etc. (or some variation).  RPG doesn't
have these ops as far as I know.  Perhaps the compiler can do some fancy
magic to enable threading but it seems unlikely.
