C＃（Xamarin）WaitHandle.WaitAny返回Int32.MaxValue（0x7FFF FFFF）

Question

WaitHandle.WaitAny方法（WaitHandle []，Int32）的文档说它返回＆＃34;满足等待的对象的数组索引，如果没有对象满足等待的WaitTimeout和等于millisecondsTimeout的时间间隔已过了＆＃34;在程序集浏览器中，我看到WaitHandle.WaitTimeout是258。

那么为什么我有时会将0x7fffffff（Int32.MaxValue）作为此函数的返回值？

这是WaitAny（）中的已知错误，还是文档中缺少的一行？

后来添加：

顺便说一句，错误发生了几次，然后就消失了，没有我做任何事情来修复＆＃34;手柄或类似的东西。

代码：

class CommandQueue
{
    EventWaitHandle m_abortRequest = new EventWaitHandle (false, EventResetMode.AutoReset);
    Semaphore m_commandCount = new Semaphore (0, 10000);

    public CommandQueue ()
    {
        m_processTask = new Task(() => Process ());
        m_processTask.Start ();
    }

    public async Task Process()
    {
        WaitHandle [] handles = new WaitHandle [2];
        handles [0] = m_abortRequest;
        handles [1] = m_commandCount;

        for (;;)
        {
            int wait = WaitHandle.WaitAny (handles, 500);
            if (wait == WaitHandle.WaitTimeout)
            {
                OnIdleTimer ();
            }
            else if (wait == 0)
            {

                break;
