 242
 243                   Note that this may overcommit CPU resources depending on the

 245                   submake jobs selected below and the number of actual CPUs present.
 246                   Example: If the main make is passed a -j4 and the submake -j
 247                   is also set to 4, we may end up with 16 parallel make processes
 248                   in the worst case.
