It doesn't seem like you're trying to perform multiple actions simultaneously. For example, you don't need to be able to read from the server and send data back at the same time. Instead, you'll have a single thread of execution. Am I right?

Not  exaclty, user code is not only SeverMessage driven but can generate messages and works on it's own (time-events, or some external events).
For example user code may generate random messages even there is no message from server, (i.e. wait for some
timeout and then feed sender with message), or do some long running events, (e.g. wait for 5 minutes), in both
of those cases one threaded pipeline is broken.
