I think it is worth poking around.  Ie for C++ (either original or MattPD
version) just takes the clock at beginning and end.  _Arguably we could do
the same inside the Rcpp call_ as he assumes away startup cost of the binary
etc pp.

Anything that leaves a whole factor on the table does something weird.  Maybe
we can learn something, maybe something odd is going on.  But we should be
ball-park comparable to other _compiled code_ examples.
