43 <para>When run, ninja normally runs a maximum number of processes
44 in parallel. By default this is the number of cores on the system
45 plus two. In some cases this can overheat a CPU or run a system out
46 of memory. If run from the command line, passing a -jN parameter
47 will limit the number of parallel processes, but some packages
48 embed the execution of ninja and do not pass a -j parameter.</para>
