+Subject: [PATCH] tests: add -j/--jobs option for run_tests.py
+
+This way it is possible to customize the number of parallel jobs to
+spawn for the tests, instead of unconditionally using all available
+CPUs. This can be helpful to run the tests without overloading the
+system.
+
+The default is still the number of available CPUs, so there is no
+behaviour change by default.
