31The new thread holds a send right for its thread kernel port.
32A send right for the 
33thread's kernel port is also returned to the calling task or
34thread in <var>child_thread</var>. 
35The new thread's exception ports are set to <strong>MACH_PORT_NULL</strong>.

39to set a processor state 
40for the thread.  Then, use <strong>thread_resume</strong> to schedule
41the thread for execution. 
42Alternately, use <strong>thread_create_running</strong>.
