Could you explain me what is a GLI and what does it mean when a thread 
is "in" and is "not" in  a rb_thread_blocking_region. And why any thread 
"not"  could block my process ? Actually I see in my threads many 
threads "in" a rb_thread_blocking_region doing waitpid which I assume 
for the others thread I launch.

Thanks,

David
