On my current system, "make test" runs in around 3 minutes, while
"./python -m test" runs in around 16 minutes. And that's with "make
test" actually running more tests (since it enables several of the
"-u" options).

The difference is that "make test" passes "-j0" and hence not only
uses all the available cores in the machines, but will also run other
tests while some tests are sleeping.

How would folks feel about making "-j 0" the default in the test
suite, and then adjusted the handling of "-j 1" to switch back to the
current default single process mode?

My rationale for that is to improve the default edit-test cycle in
local development, while still providing a way to force single-process
execution for failure investigation purposes.

Cheers,
Nick.
