Good point. This is definitely misleading. I wonder if the _th naming
is a good idea anymore though given that the bottom half (in the traditional
sense) is now a thread based call and hence the th might be confusing?
Perhaps the h and thread naming used in the pollfunc code would be clearer?
Lars, this bit was yours originally. Any thoughts?
