And invoke it as above, replacing "HOL" by "Pure" in the command line.
BTW, in this tty mode the nominal number of worker threads is determined as follows:

The default for Multithreading.max_threads is 0, so the actual value will depend on the number of hardware threads, topped by 4. You can also assign specific values 4, 8, 12, 16 as you see fit.
