[Rcpp-devel] Have I noticed memory management bug in RcppArmadillo or is this the intended behaviour?

Looks like we emailed in parallel.  

What I just sent back to you and the list should work the same way on Windoze
using Rscript instead of littler, and the task manager to read out memory
use.  While you (as I recall) don't get microbenchmark you can still get a
stab at the measurements from your end.
