RCU (read copy update) is a technique for improving scalability of data structures.
It has been problematic because of patents though. Many corporations felt it was too risky to use it. Most (or all?) of the relevant patents expired, so we could reconsider this.
First thing to find out if whether the patent situation is resolved.
2nd question is: do all platforms (incl Windows) support urcu?

The linux kernel uses a flavor of RCU (https://lwn.net/Articles/262464/) so they may have solved or circumvented,
the patent issue. Perhaps a way to go would be to take inspiration from how they did this or to ask in
#kernelnewbies on oftc.
