soup_session_queue_message() and soup_session_send_async() are just
different ways of doing the same thing. soup_session_queue_message() is
simpler to use in the case where you want to request a resource and then
process it all at once after the whole response has been received.
soup_session_send_async() is simpler to use in the case where you want
to handle the response a little bit at a time as it's being received. So
it sounds like you want the latter.

The docs aren't meant to be "discouraging" multi-threading; you just
need to understand what operations are and aren't thread-safe (in
particular, it's ok to send multiple requests from multiple threads, but
you mostly can't work with a single request from two threads at the same
time).
