当我在我的程序中使用Parallel.ForEach时,我发现有些线程似乎永远不会完成.事实上,它一直在反复产生新线程,这种行为是我没想到的,绝对不想要的.

我能够使用以下代码重现此行为,就像我的"真实"程序一样,它们都使用处理器和内存(.NET 4.0代码):

public class Node
{
    public Node Previous { get; private set; }

    public Node(Node previous)
    {
        Previous = previous;
    }
}

        DateTime startMoment = DateTime.Now;
        int concurrentThreads = 0;

        var jobs = Enumerable.Range(0, 2000);
        Parallel.ForEach(jobs, delegate(int jobNr)
        {
            Interlocked.Increment(ref concurrentThreads);

            int heavyness = jobNr % 9;

            //Give the processor and the garbage collector something to do...
            List<Node> nodes = new List<Node>();
            Node current = null;
            for (int …
