In my experience, running tests sequentially is unsafe. I prefer to use -j1:
"Run tests in parallel using 1 child processes"

A new process is spawned for each test file. It reduces the risk of
side effects between 2 test files.

Putting the architecture names in would definitely make a lot of sense.

Cheers,
Nick.

Thanks for the tip.  I was curious if there was a difference between -j1 and sequential.
There is a -j1 in tools\buildbot\test.bat that provides a default unless overridden in the buildbot master config.
I still see the -j1 being passed in the buildbot logs for the Windows arm32 buildbot.
