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!
