 245
 246                   Note that this may overcommit CPU resources depending on the

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