Oh, I try running ioserv.reset(); ioserv.run(); after the two joins
and this time it works as I excepted.
Thank you very much.

By the way, I see this statement in boost::asio::io_service::reset  
document:

This function must be called prior to any second or later set of  
invocations of the run(), run_one(), poll() or poll_one() functions when a  
previous invocation of these functions returned due to the io_service  
being stopped or running out of work.

I didn't notice this before... orz
