Thanks! Perhaps it would be cool for my better understanding to know why 
actually the IO operations are blocking??

I tried to make a simple debugging tool to simulate a simple HTTP request 
and dump all to my screen. I thought it would be a twoliner but then the 
blocking issues appeared.. :((

thanks!
