asio::async_write() is a convenience function that calls
socket::async_write_some() multiple times - until all the data is
sent. This means that if you issue multiple asio::async_write's, the
data will be interleaved in most cases.
As for multiple async_write_some(), it will probably work on some
platforms... But note that async_write_some doesn't promise to send
all your data. So you can't "fire and forget" anyway.
