Java is not made for running 30000 threads, so that comparison makes no 
sense, does it.

Since I'm new to Erlang, I was just assuming that my erlang code was 
wrong and there would be a more efficient way of finding a '\r\n' in a 
stream. If there isn't, then that's fine for me; but I just wanted to 
make sure, so I asked.

I'll try the +native now.
