Espruino restarting on many IR signals recieve (watchdog retsarting)

[espruino-discuss]

Hello,
I am quite new to Espruino, (was similar to Arduino) and I really like Espruino more than Arduino.

So, I have written a simple code from examples -

var led;

require("IRReceiver").connect(5, function(code) {
  if(code=="100000000111111110101100010100111") toggle();
  //console.log(code);
});
function onInit() {
  console.log("init running...");
  digitalWrite(4, 1);
}
function toggle() { 
  led= !led; 
  digitalWrite(4, led);
}
save();

This code works really well. It reads signals and does his job. But, when I press button for 50 or 60 times, board restarts and says -

I know that cause: 4 is watchdog reason. Also I know that ES8266 is not such powerful board to handle working on big data. And also I know that when it turns led, watchdog can trigger at that moment and if many of those situations will be, buffer simply goes full.

So, my question is - how I can fix this issue so that if I will press button for 500 times restart must not appair? Something that will stop watchog receiving data when board does another operations? I tried to do this with transistor - when I pressed button and code was recognized, transistor was shutting down IR receiver, but the problem was same.
