984831620c
This uses multiple concurrent TCP connections by making the state of the connection including the output buffer a part of the application data. This leads to the buffer, to be sent length of data and the already sent data to be part of that state and must be handed over to functions that generate data. At this point this leads to an overuse of OSEG and DSEG memory space so further work needs to be done on tuning the code. Putting it into a branch for now.
