I am able to reproduce it on my Mac and as below the values of os.getpid() are
the same with the command. I will try to get to a Linux box to see if I can
reproduce this. I was always under the assumption that -j 4 runs tests in
parallel as it even says in the message "run tests in parallel using n child
processes" . Maybe I am stumbling upon a mac os specific issue or understanding
something wrong about the regrtest framework. I am using Macbook pro with
Mojave.
