> Improve the JavaScript binding's internal Event loop and add additional tests.
> The addition of JavaScript soak/performance tests msgr-send.js and
> msgr-recv.js, which mirror tests of the same name in C and Python flagged up
> a few edge cases that caused sporadic failures. The problems seem to be
> related to the ws WebSocket library directly calling some callbacks rather
> than posting to the JavaScript internal Event queue. The effect of calling
> directly mean that the main message handler and the close handler could
> actually get called *concurrently* which is clearly a bad thing and somewhat
> undexpected in JavaScript..... The improvements here add a number of guard
> tests and introduce a setTimeout that allows the "real" close handler to be
> deferred by posting it onto the Event queue.
> msgr-send and msgr-recv have been run with counts of several million messages
> and also with message sizes of up to 2MB and everything seems stable now.
