The changes in GCC 11.x made `std::condition_variable` implementation internals `noexcept`. `noexcept` is known to interact particularly bad with `pthread_cancel`, i.e. `__cxxabiv1::__force_unwind` passing through the `noexcept` call stack frame causes a `std::terminate` call and immediate termination of the program Digging through the GCC ML archives[1] lead me to the idea of patching this with a few pthread_setcancelstate's. As bad as the solution is, it seems to be the best we can do within C++17 limits and without major rework. [1]: https://gcc.gnu.org/legacy-ml/gcc/2017-08/msg00156.html
