------------------------------------------+---------------------------------
 Attached is a test program that demonstrates some curious behavior I see
 while using serial port on a Linux system (epoll reactor).

 The order of operations is: create serial_port, call async_write to send
 some data over the port, call cancel to cancel the write operation, enter
 io_service.

 I would expect the write completion handler to be called with the
 error_code argument set.  Instead, no error_code is set and some bytes are
 transferred.
