Здравствуйте,

Спасибо заранее за ответы.

Есть wrapper:

    public class SyncQueue {
        object sync_obj = new Object();
        Queue inner_queue = Queue.Synchronized( new Queue() );
        WaitHandle[] h_wakeup = new WaitHandle[ 2 ] {
            // see the constructor comments
            null,
            // awakes awaiting threads when the queue is not empty
            // initially it's non-signaled
            new AutoResetEvent( false )
        };

        public virtual void PushBack( object obj ) {
            // the inner_queue is synchronized, so we do not worry
            // when adding a new object
            inner_queue.Enqueue( obj );
        }
        public virtual object PopFront() {
            object result = null;
            // ensuring that no more than 1 object will be awaken
            lock ( sync_obj ) {
                // awaiting either the termination event or the event,
                // signaling this thread to wake up
                int h_no = WaitHandle.WaitAny( h_wakeup );
                // if the termination event has not occured do pop()
                if ( h_no != 0 ) result = inner_queue.Dequeue();
            }
            // return null if the termination event has occured or
            // return object if the queue has been updated
            return result;
        }
        // h_terminate - is a handle which is non-signaled state
        // by default; it is to terminate a thread awaiting a
        // new request being queued; it is designed to terminate
        // awaiting threads when the server is stopped
        public SyncQueue( WaitHandle h_terminate ) {
            this.h_wakeup[ 0 ] = h_terminate;
        }
    }

Когда из какого-то thread'а вызывается PopFront() и очередь пуста, thread уходит в wait, 4то правильно, НО! при этом CPU usage — 100% и комп умирает как на бесконечном цикле.... Никто не сталкивался??
