  Hi manuel,

i think the threads are terminated when the destructor of the io_service 
is called. Creating threads is too expensive, to kill them everytime the 
program is idle. So they are usually left in a blocked state.
You can try this by putting an iostream into brackets {} and set a 
breakpoint afterwards.

If the threads are still running, they might be killed using an old 
C-technique, called atexit().
