Workers

• JS/TS already has a strong worker-first story
• already talked about local / shared heap split
• shared memory across workers, local heap to each worker
• (this is fortunate because it gives us the local managed/borrowed model we want)
• retain local / worker isolation as the primary model
• use Workers for structured concurrency
• (maps to threads N:M)
