title: Multi-threading in NLOPTR (The R package interface to NLOPT)
body: <p>I'm trying to run a set of fairly large non-linear optimizations through an R interface.  (Yes, it must be R -- other languages don't work) I've been groveling around in the code, and I confess that I can't figure out whether NLOPT supports multithreaded operation, and, if so, how it gets kicked in.</p>
  
  <p>Is it?</p>
