  * the call is request_forget().
  *
- * The request_process() callback will be skipped if the callee terminates
- * before picking up the request. In this case, the terminating task will
- * cleanup its incoming calls list and so the next callback invoked on the call
- * will usually be answer_preprocess(). If, in the meantime, the caller
- * terminates too, it may happen that the call will be forgotten instead of
- * answered, in which case the kernel will invoke the request_forget() and
- * answer_cleanup() callbacks instead. The order in which they are invoked is
- * not defined. 
- *
  * The comments for each callback type describe the specifics of each callback
  * such as the context in which it is invoked and various constraints.
