#!/usr/bin/env node

"use strict";

console.log("This is pid " + process.pid);

setTimeout(function () {
    process.on("exit", function () {
        require("child_process").spawn(process.argv.shift(), process.argv, {
            cwd: process.cwd(),
            detached : true,
            stdio: "inherit"
        });
    });
    process.exit();
}, 5000);

Only this one solution allow helped me to prevent memory leak in nodejs, argh! Thank you!
