I was able to reproduce the problem you described, but the cause is 
actually a small error in your program. The program starts new 
async_receive_from operations in both handle_receive_from and 
handle_send_to.

If you start multiple reads on a socket, they are added to an internal 
queue and complete in order as data arrives. In the program the length 
of this queue is increased by one for every packet that gets echoed.

I think all you need to do to fix the leak is to remove the 
async_receive_from call from handle_send_to.

Cheers,
Chris
