...it: repeated assignments of large arrays used in a loop. If it's complex, skip it --- the behavior will be no worse than current. By the way, what's happening with Luke's refcnt patches? From the outside, they seem like a great improvement. http://homepage.stat.uiowa.edu/~luke/talks/dsc2014.pdf http://developer.r-project.org/Refcnt.html Are they slated to become the standard approach? Are they going to be dropped? Will both approaches be kept in parallel? > Unfortunately, that seems not to be safe, because it's > possible that there is a reference to the no-longer-needed...
