summary

Implements a novel virtual continuation scheme that assigns virtual addresses to stack-allocated handlers and mediates effect invocations via a software MMU (SMMU). Provides an operational semantics and a correctness proof, compiles into a new runtime/compiler called MultiLexer, and compares against BaseLexer; overhead of zoning is a small constant per resume and benchmarks show real parallel speedups when multishot resumptions run on multiple threads. Artifacts and reproducible evaluations are available.
