What kind of multithreading does emscripten support?

Emscripten has support for multithreading using SharedArrayBuffer in browsers. That API allows sharing memory between the main thread and web workers as well as atomic operations for synchronization, which enables Emscripten to implement support for the Pthreads (POSIX threads) API. This support is considered stable in Emscripten.
Keeping this in consideration, which is the main application thread in Emscripten?
The main browser thread is where web pages start to run JavaScript, and where JavaScript can access the DOM (a page can also create a Web Worker, which would no longer be on the main thread). The main application thread is the one on which you started up the application (by loading the main JS file emitted by Emscripten).
Consequently, is the Emscripten pthreads demo compatible with threads? The Emscripten pthreads documentation contains relevant documentation for multithreading. Threads are supported in some (but not all) browsers. Configuration changes may be required. The [1] demo can be used to determine if thread support is available.
