Yes, and fixing that made me realize the other Problem which I
wanted to solve using a separate thread. (^_^)

Hmm, ok so it's not a good idea to use threads in this case...
So how about this:
Instead I could create a pipe and fork so I would do the communication
with nas in a separate process and write the audio data to the pipe.
I would probably need another pipe for communication (emulating ioctls).
