I don't know how spirit works internaly - the example above could be useful
if spirit reads from a stream (usually parsers read pattern
from a continuous stream of characters).
The idea is that the stream_buff used by the stream runs in a coroutine and
suspends the corutine-context if not enough characters
are available (from socket, in buffer).

Another possible solution would be using the async_result feature from
boost.asio (1.54) - but this depends how spirit works.
