You will get this assertion whenever you use any Windows services that
maintain a thread pool. COM/RPC is one of the examples. The problem is the
threads from these pools are still around when main returns. I have not
found out a way to control these threads. What I have done is to call
on_thread_exit at the end of all my thread routines. In a way, this has
rendenered automatic thread local storage cleanup on Windows
useless(remember all those heated discussion about static boost::thread
