See https://github.com/emscripten-core/emscripten/pull/9579
in which we propose to throw when doing a pthread_join or another operation on the main thread which can block for a nontrivial amount of time. The possible deadlocks that can hit have been a serious problem for new users of pthreads on the Web. You can still use pthread_join etc. on the main thread, you just need to flip a flag. The error by default points people to the docs that explain the possible risks, and hopefully encourages people to use alternatives (like not blocking, or using PROXY_TO_PTHREAD, etc., all mentioned in those docs). This will slightly inconvenience existing users (that will see an error and must then flip the flag) but should help new users avoid confusing deadlocks, which I think is a reasonable tradeoff.
