Yes, it introduces a whole new range of multithreading issues also to JS land. However I think threading issues won't be as common as in C++/Java/C# land, since the only thing that will be shared between threads/workers is byte arrays -> There's no shared access to other Javascript objects. As most normal JS developers won't be dealing with plain byte arrays the potential for misuse is not too high.
