代码如下：

var sigintCount = 0;
var productArray = [];
var productArrayLen = 0;
var productLock = false;
var PRODUCT_ARRAY_THRESHOLD = 10;

var producerTimer = setInterval(function () {
		if (!productLock) {
			if (!productLock) {
				productLock = true;

				if (productArrayLen < PRODUCT_ARRAY_THRESHOLD) {
					productArray.push('product');
					productArrayLen++;
					console.log('product:' + productArrayLen + '   producer.push');
				} else {
					console.log('product:' + productArrayLen + '   producer.idle');
				}

				productLock = false;
			}
		}
	}, 500);

var consumerTimer = setInterval(function () {
		if (!productLock) {
			if (!productLock) {
				productLock = true;

				if (productArrayLen) {
					var product = productArray.shift();
					productArrayLen--;
					console.log('product:' + productArrayLen + '   consumer.pop');
				} else {
					console.log('product:' + productArrayLen + '   consumer.idle');
				}

				productLock = false;
			}
		}
	}, 1000);
