1. As I pointed out earlier, there's no need to know *exact* when the blocked thread wakes up again.

There is if you're trying to shut down an application. I don't know how many times I can point out the same thing; perhaps with a simple example - you have a service with a thread that needs to clean up before the service can shut down - by having to wait for the thread to finish, you could trigger the "Service could not be stopped, blah blah blah" message.

THUS FAR there isn't ONE SINGLE argument that justify against use of Thread.Sleep against SCENARIO 2.

public class Utility
{
  private static readonly object SyncLock = new object();

  public void WaitForTime(int milliseconds)
  {
    lock (SyncLock)
    {
      Monitor.Wait(SyncLock, milliseconds);
    }
  }

  public WakeAllThreads()

    lock (SyncLock)
    {
      Monitor.PulseAll(SyncLock);
    }
  }
}

why the appreciation? It's more code than a simple while loop with a Sleep.

new Utility().WaitForTime(5000);

why you want be thankful when there really isn't a justification for it?
