Bug #6575: Thread#kill sets rb_errinfo() to Fixnum 8 after rb_protect(function, data, &error_tag)

Using rb_protect() I've realized that when the thread is killed by other thread using Thread#kill, the error_tag passed to rb_protect() is set to 8 and rb_errinfo() returns Fixnum 8:


  ret = rb_protect(function, data, &error_tag);

  // While executing function() in Ruby land, our thread is
  // killed by Thread.kill.

  // If now I inspect rb_errinfo() it returns Fixnum 8, and 
  // error_tag it's set to integer 8.


Is it the expected behaviour? Wouldn't make more sense rb_errinfo() to return some kind of a new exception ThreadKilledException or whatever instead of Fixnum 8?
