Very good catch.  The 'Rcpp_precious_remove' was spurious as I suspected all
along but it was trickily hiding the actual issue.  Any clever thought on how
we could check for missing .libPaths() etc when RInside starts?

I think you can control that by setting the 'interactive' toggle. From
memory, there is a global state variable reflecting the command-line choice
(or invocation) and IIRC the ctor may offer it. I have the same behaviour in
littler where we long ago decided to have interactive=false (because hey,
scripting) and that sometimes leads to slightly different outcomes so we have
an override there.  And RInside and littler are pretty close cousins.
