Some people use "make test ARGS=-j4". Does it work?

The right solution would be for ctest to integrate with GNU make's 
jobserver feature. If you have 4 cores available, you do not want to 
tell ctest to use them all, but to share them with other make targets 
which might be running at the same time.

Unfortunately I have not found whether this is possible.
