That may be true for applications that aren't particularly demanding,
but tends to fall down with more demanding applications.
1) Writing a multithreaded application does not guarantee that different
threads go on different CPUs (assuming the CPU's are even
there :-)
2) As the demands of the application go up (eg allowed processing time
decreases, data throughput increases), it is more likely that
automated schedulers will not help achieve required performance,
even with multiple CPUs.
