It seems that if my thread_pool will not spawn its own threads, but
instead provide a run() method, it will become similar (though not
identical) to asio::io_service. This is an interesting idea for me. I'm
quite fond of it.

At first sight it seems my dispatcher classes have the benefit of being
able to wait on multiple tasks (handlers) being executes concurrently.
Is that true? If so, do you see that as an important advantage?

Do you think that this functionality (of
thread_pool/dispatchers/asio::io_service) should be in Boost.Thread?
IMHO, it sounds as if it has more to do with "multi-threading policy"
than "I/O (sync or async)".
