If I run "make -j4" here, it works (on the default branch).

Thanks, glad to see that this was added! :)

This looks like a feature that was added in 3.5.  Rather than passing the flag to setup.py from the Makefile (where I had been looking for it), setup.py looks at the MAKEFLAGS environment variable and turns on distutils.common.build_ext's parallel flag if "-j" is found in that. By default it will then do a parallel build using os.cpu_count() number of tasks.
