  21  *
  22  * - Statistics: we are supposed to be keeping various counters.  we aren't.
  23  *
  24  * - Async RPC: Unimplemented.
  25  *
  26  * - The NT "ports" API, aka LPC.  Greg claims this is on his radar.  Might (or
  27  *   might not) enable users to get some kind of meaningful result out of
  28  *   NT-based native rpcrt4's.  Commonly-used transport for self-to-self RPC's.
