调试时无法重启

[lyzz0612]

升级了vscode版本到1.40.1或1.40.2，之后调试时点击重启按钮直接关闭没反应。开发工具日志如下：

SIGUP的确是不存在此signal，猜测应该为SIGHUP。 但改为SIGHUP后出现新的报错

ERR Error: kill ENOSYS
    at ChildProcess.kill (internal/child_process.js:476:13)
    at LuaDebug.disconnectRequest (c:\Users\ASUS\.vscode\extensions\wellshsu.luaide-lite-0.2.0\out\src\debugger\LuaDebug.js:133:31)
    at LuaDebug.dispatchRequest 

不传signal使用默认值SIGTERM则好像无法关闭子进程，尝试了另外几个signal后，发现和此issue表现一致

暂时的解决方案：

    disconnectRequest(response, args) {
        this.sendEvent(new vscode_debugadapter_1.OutputEvent("Server is shutdown.\n"));
        if (this.luaStartProc) {           
            try {
                this.luaStartProc.kill("SIGHUP");   //会报错但能关闭子进程，加catch使其不中断能正常重启
            } catch (error) {
            }
        }
        super.disconnectRequest(response, args);
    }
