I Sleep You 3000

the current 'wait x seconds' for Espruino blockly doesn't always work as intended.

for example, if a while(true) loop containing a wait x seconds block, for javascript, it doesn't really wait for the setTimeout function and will just immediately execute the next iteration.

e.g. the attached image will be converted to:

while (true) {
    setTimeout(function() {
        digitalWrite(LED, 0);
        setTimeout(function() {}, 1000*1);
    }, 1000*1);
}

Which is pretty confusing for the blockly user

So I implement a sleep function as stated in https://stackoverflow.com/a/16624104/632­26

var sleep = function (miliseconds) {
   var currentTime = new Date().getTime();

   while (currentTime + miliseconds >= new Date().getTime()) {
   }
}

It works when I execute like sleep(1000) or sleep(2000), but for sleep(3000) the nodeMCU resets itself.

Is there a max execution time that forced the nodeMCU to reset? if yes, then how to increase it?

Thanks
