Generally, I think he means "not responding". I agree, however, that's
not very clear. Does it mean not receiving user input, or not using any
CPU time or...

The phrase "not responding" isn't very clear either. What does "responding" mean? For a thread with a message pump, this often (though not necessarily) means that the thread is pumping messages. But most threads don't have a message pump. And many types of threads can sit and process for long periods of time without ever interacting with any other thread. Are those threads "not responding", even though they are working exactly as designed?

That said, it should not be necessary for you to do this.  You will  
probably get better advice if you explain why it is you think you want to  
do this and what you hope to accomplish.

I would imagine he's looking for a heartbeat sort of mechanism to see
whether a program has "died" and needs to be restarted. Having written
more than my share, it sounds like the description given.

Well, only Gidi can elaborate. Thus my question. We can speculate until the cows come home, without a more descriptive question I don't see any way to offer practical advice.
