I tried to do this some time ago.  My conclusion then is that it
cannot be done with a guarantee, because R can exit in different ways.
 I implemented what I had an came up with an onSessionExit() method
available in R.utils.  Check that out for a start.  It modifies
.Last(), but that can be circumvented by quit(callLast=FALSE).
