comment by AgentME · 2026-05-27 · in Theseus: Translating Win32 to WASM

There is a proposal to add threading to WASM itself https://github.com/WebAssembly/threads/blob/main/proposals/t... But that’s not going to help when accessing the DOM.

Useful info is here: https://github.com/WebAssembly/threads/blob/main/proposals/t... Atomics are well covered. The "wait" and "notify" primitives map efficiently to mutexes. "Blocking on the main thread is not allowed, so we can't call…
