Actually , I tried :

rb_funcall3(rb_const_get(rb_cObject, rb_intern("Thread")), 
rb_intern("new"), 0, 0);

But >> `initialize': must be called with a block (ThreadError)

it seems like the Thread Class  should always be  called with a Block of 
instrcution to execute as we do with Ruby Code Thread.new{ do .. this .. 
ect }


I found Some C Methods to deal with Ruby Thread :
...
VALUE   rb_thread_stop (void)
VALUE   rb_thread_wakeup (VALUE)
VALUE   rb_thread_run (VALUE)
VALUE   rb_thread_kill (VALUE)
VALUE   rb_thread_create (VALUE(*(ANYARGS), void *))
void   rb_thread_interrupt (void)
void   rb_thread_trap_eval (VALUE, int)
void   rb_thread_signal_raise (char *)
int   rb_thread_select (ANYARGS)
void   rb_thread_wait_for (ANYARGS)
VALUE   rb_thread_current (void)
VALUE   rb_thread_main (void)
...
http://ruby-doc.org/doxygen/1.8.4/group__ruby__eval.html

But not yet sure that it really create and manage a Ruby Thread ( 
especially that this One should be always initialized with a block of 
instructions )
