A DESCRIPTION OF THE PROBLEM :
The Monitor.TryEnter method in .NET is brilliant. It allows you to set up a synchronized block that gets skipped if the lock is in use, otherwise it will acquire the lock and continue. It has both a default version and a timeout version.
Here is an example from the help using the default version:

    //Check if the queue is locked.
    if (Monitor.TryEnter(m_inputQueue) == False)
      {
        AddElementWithoutWait = False;
      }
    else
      {
        m_inputQueue.Enqueue(qValue);
        Monitor.Exit(m_inputQueue);
      }


The other version(s) of TryEnter allow you to pass in a time to wait for the lock. This would be a great feature to be able to use even just for things like threading in Swing. It is not 'syntactic sugar' as far as I can tell.
