That is true... your original post seemed to imply a 2x overhead in
number of processes.  If you do 8 pthread_create() calls, no matter
who (which thread) does them, you will end up with the parent, the
8 new threads, and one for the 'thread manager' as you call it.  So
the overhead is always one extra thread for the task that gathers
results when threads terminate to take care of the 'join' operation
that may be done...
