sage-maketest and sage-test-new should be able to run tests in parallel

[qed777]

Reported on sage-devel by K.-D. Crisman:

Subject: can sage -testall use threads?

That is, without setting NUM_THREADS or something.  I tried

./sage -testall -p 8

but I just get lots of error messages in addition to my test output.
I guess I have the same question about sage -tnew as well.

Somewhat related: #279

It seems the sage -testall and sage -tnew operators invoke SAGE_LOCAL/bin/sage-maketest and sage-test-new, respectively. To run the tests, both scripts use sage -t, which calls the serial doctest runner sage-test. Moreover, sage-test-new does not pass along command-line arguments.

This is resolved by #12415.
