Common c++ Thread::notify implementation question.

[Jim]

I'm a bit hazy as to what exactly one would do with this method.  I'm in 
need of kicking off a detached thread and somehow being able to tell 
when it finishes.  Since a detached thread is self deleting, it's 
dangerous to attempt to call any methods after the detach or you risk a 
segfault.

So I see the parameter to the notify method is the thread that as 
terminated.  I'm not sure of what can be done with it at this point.  Is 
this the same thing you would obtain with a call to the static get method?

The documentation says it "sends a notification to the parent".  Can 
someone explain how this might work?  A simple example might be nice.

Thanks,
Jim.
