Calm down ;-) I've done these tests myself. I was wondering about code 
laking the characteristics which trigger polling. I know, that's pretty 
rare and maybe not doable, but is a question that comes to my mind.

It's not stated. It's stated that without -gnatP, it doesn't work, and 
with it it inserts calls to the polling function under several cases 
(enough cases, I could agree).
