 The following program does not terminate.

 {{{
 #include <boost/asio.hpp>

 int main() {
     auto* ios = new boost::asio::io_service;
     auto* port = new boost::asio::serial_port(*ios);
     port->open("COM6");
     char c;
     boost::asio::async_read(*port, boost::asio::buffer(&c, 1),
 [](boost::system::error_code, int) {});

     delete ios;
 }
 }}}

 Despite the fact that the io_service is not running, its destructor hangs
 if there is a pending async_read from a serial_port. If that read
 completes (by receiving one byte), the program terminates.
