Only if you're using a totally braindead implementation of make. The whole point of the jobserver pipe is to eliminate this fanout problem.
So I might regularily use maybe -j 10 (when I know 10 more calls to make are made) On some machines this might be unacceptable and bring them to their knees.On other machines it can work really well.
