My (limited) understanding is that asm.js doesn't allow blocking code, which means it's not a good fit for a Posix like model with a main function which calls out to external services. (I'd love to be wrong here.)

I hear that there's a plan for some form of limited shared-memory concurrency which might be abusable to allow threads, but I haven't made much of the designs.
