//   "f(closureType, non_virtual)"

// where "closureType" is the name of the particular subclass of ExtendedOopClosure,

// and "non_virtual" will be the string "_nv" if the closure type should

// have its "do_oop" method invoked non-virtually, or else the

// string "_v".  ("ExtendedOopClosure" itself will be the only class in the latter

// category.)
