  // Now drop the reference to the custom operation object.
  // This is necessary so that custom operation objects can be created
  // on the stack for synchronous custom requests.  If we do not do this,
  // then there is a race condition which could result in the stack-created
  // custom operation object having a reference count of 2 when it falls
  // out of scope (and destructs).  Our op_ data member would be the one
  // that held the other reference, and when our op_ data member destructs,
  // it attempts to perform a _remove_ref() on the underlying operation
  // object - which has already been destructed!  Thus, we reset the op_
  // data member here to the 'nil' state - causing the _remove_ref() to
  // be performed now.
  this->op_ = 0;
