...

if I run the example boost_asio/example/http/client/async_client.cpp on a Windows 7 or Vista and set a breakpoint on the very last line (return 0;), VisualStudio tells me that (apart from the Main Thread) two Threads named Win32 Thread are still running.

These are internal asio threads.

...

My concern is, that a project which uses a lot of socket connections will end up with a dozen or more lingering threads. How can I avoid that?

No, AFAIK, the amount of these internal threads doesn't depend on the count of open sockets. You can open and close sockets/timers and see that you still have these 2 additional threads.

You're right, the number of threads doesn't increase when I create more clients. Still, I'd like to know when these threads terminate. Do they nescessarily run until the app exits, or is there a way of telling asio 'hey, I'm done with sockets now, no need to keep these threads running'. Thanx! manuel
