Those linked lists give some nice guarantee that significantly simplify a lot of code and give some guarantees that you just can't have otherwise.
Context switching can be expensive, but I don't see what's specific about managed envs about that. Fundamentally you have to have trust in code, and need to have the hardware support to enforce authenticity of the trusted code in order to avoid context switching. Maybe a promising development is CPUs growing more and more cores, and more and more kernel resources being available through io_uring and similar interfaces.
