+		  Example: If the main make is passed a -j4 and the submake -j
+		  is also set to 4, we may end up with 16 parallel make processes
+		  in the worst case.

+		  You get maximum build performance, if you set the package build
+		  jobs to the number of CPUs (cores) available and also start the main
