Still to do:

* Handle multiple SM_MON requests that are identical save for the "priv"
  information.  How should I do this?  No spec's...(it's not really
  supposed to happen).

* Check for stack overwrites, etc.  (Biggie!)

* Use RPC calls other than (simple!) pmap_rmtcall() when sensible...

* Better/smarter callbacks?

* Forking startup for initial notify list?

* Forking for callbacks?  (This one is tougher...)

* BETTER CODE COMMENTS!
