Sorry, but in the three years that have intervened, my brain has paged out the relevant context. As I recall, there were issues with some of your changes to arc4random() and I proposed tracking OpenBSD's implementation more closely. If everyone's in agreement on that, please go ahead and commit the changes. On a related note, I recall that the biggest issue is that getpid() overhead now dominates the cost of arc4random(). The title of this thread suggests a simple solution!
