How would mcfgthread implement the `<rcu>`?

[void2012]

As C++26 is finalized this year, user-space RCU (sync mechanism from the guts of the modern linux kernel) has officially landed in C++ standard library https://en.cppreference.com/cpp/header/rcu

As I wonder on how could it be implemented on windows, I also want to ask if there are plans to implement it within mcfgthread as a backend for libc++/libstdc++ implemenetations. Is there anything being worked on regarding future <rcu> implementation? Thanks!

It depends on whether it's gonna be implemented on abstraction of gthr-*.h, or on Windows API directly like std::thread::hardware_concurrency().
