+  Asynchronously raise an exception in a thread. 
+  The \var{id} argument is the thread id of the target thread;
+  \var{exc} is the exception object to be raised.
+  This function does not steal any references to \var{exc}.
+  To prevent naive misuse, you must write your own C extension 
+  to call this.  Must be called with the GIL held. 
+  Returns the number of thread states modified; if it returns a number 
+  greater than one, you're in trouble, and you should call it again 
+  with \var{exc} set to \constant{NULL} to revert the effect.
+  This raises no exceptions.
