That's my view as well. IMHO, it makes no sense at all to run a TCP application thread at a higher priority than the TCP state machine. If part of that application needs a high priority, then this part should get it's own thread.

Be aware of the cooperative nature of Nut/OS threads. If you need realtime behaviour, you have to use interrupts in most cases.
