@jwseigh I thought that membarrier only guaranteed ordering, but perhaps you have a trick that I missed.

@jwseigh Nice! But if I may ask, how does this deal with the possibility that a updater on some other thread concurrently changed the pointer that you are trying to protect?

Today I learned that gawk has a "--debug" command-line argument, and has had for more than ten years. In my defense, I using awk for about 30 years prior to that...

@Louson Never forget: It is easier to circle the square than to square the circle.

@jwseigh Rightly or wrongly, this site says tau is 2π. https://en.wikipedia.org/wiki/Tau_(mathematics)
Me, I glanced too quickly at the first occurrence of 𝜏 (tau) in this thread and mistook it for the Roman-alphabet letter "r". ;-)

@tommythorn Indeed, 2π day and 𝜏 day are one and the same! But I suspect that more people would prefer to eat two pies than would prefer to eat a tau. ;-)

@morgan I would attempt a witty response, but I would probably end up sounding like a square. ;-)

@brauner RCU uses many mutexes so that RCU users don't have to? ;-)

@ljs It is amazing how destructive unanticipated use cases can be. Destructive, but necessary...

@jann @brauner Or to recover from the next timeout being unduly delayed, for that matter. That said, in my experience, most timeout handlers unconditionally do their work. On the other hand, I could easily believe that unconditional timeout handlers are much less likely to come to your attention. ;-)
