[Diffusion] rL248282: test runner: Unix systems now put inferior dotest in its own process group.

Hey Zachary,

There is a Windows-specific subprocess.CREATE_NEW_PROCESS_GROUP flag that you could potentially add to the Windows branch of the suprocess creation call in dosep.py. I’m not sure how useful that is on the Windows end as this is mostly about console signal isolation, but I thought I’d call it out in case you were interested in adding that to the Windows inferior dotest.py creation.

Thanks for the heads up, I’m familiar with the flag. I’ll look into whether it’s appropriate when I get back from CppCon

Okay!
