You are correct.  When spawning additional threads, should an idle CPU
be available, it's very doubtful that the new thread will show any bias
toward the original thread's CPU.  Most modern OS's do run each thread
within a process spread across n-CPUs.  Those that don't are probably
attempting to modernize as we speak.
