Haha! I'll remember that one! :).

I do agree with you!

This class of lockless algorithm can bring more edge cases and cause tremendous
amount of work to debug them often not easily reproducible. The Tor project is
too "sensitive", I think, to hit those kinds of issue in production so normally,
before adding RCU data structures, a huge number of tests has to be done.

Anyhow, you are right, it should be done with the two options at least. We'll
see if RCU brings a significant performance/scalability improvement before going
"full throttle" with it.

Cheers!
David
