make -j 4 is really make -j 8 for buildworld?

Hmm.. From the manual page:

     -j max_jobs
             Specify the maximum number of jobs that make may have running at
             any one time.  Turns compatibility mode off, unless the B flag is
             also specified.

'maximum number of jobs' seems to be quite clear to me... Or is the -j
propagated into subdirs ?
