It's worth noting that this is not the only way to do clean shutdown.
The new HTTP server examples ("server2" and "server3") also perform a
clean shutdown. However, rather than explicitly closing the connections,
they simply rely on the fact that the io_service destructor will destroy
all handler objects associated with unfinished operations.

What is scheduler? Is it an io_service? If so, by explicitly stopping it
some of your completion handlers will never be called. If you want to
use this particular clean shutdown design, it is better to wait for the
io_service::run() call to finish automatically once all the outstanding
operations have finished.
