289 This adds a -jX option to certain packages that are known to

291
292 Note that this may overcommit CPU resources depending on the
293 -j level of the main make process, the number of package
294 submake jobs selected below and the number of actual CPUs present.
295 Example: If the main make is passed a -j4 and the submake -j
296 is also set to 4, we may end up with 16 parallel make processes
297 in the worst case.
298
299 You get maximum build performance, if you set the package build
300 jobs to the number of CPUs (cores) available and also start the main
301 make process with -jX, where X is the number of CPUs (cores).
