C# 使用WinRM在目标计算机上同时运行PowerShell命令

我正在尝试在目标计算机上同时远程运行多个PowerShell命令

var connectionInfo = new WSManConnectionInfo();
var runspacePool = RunspaceFactory.CreateRunspacePool(1, 10, connectionInfo);
runspacePool.Open();

var waitHandles = new WaitHandle[10];

for (int i = 0; i < 10; i++)
{
    var powerShell = PowerShell.Create();
    powerShell.RunspacePool = runspacePool;
    powerShell.AddCommand("Some-long-running-command");
    var asyncResult = powerShell.BeginInvoke();
    waitHandles[i] = asyncResult.AsyncWaitHandle;
}

WaitHandle.WaitAll(waitHandles);            

runspacePool.Close();

执行此代码时，将在目标计算机上创建多少进程和线程？ 如何在一个进程/连接中在目标计算机上创建多个线程
