I know that. You could argue whether lwIP is the problem here or the FreeRTOS 
API :-)
Are there any other OSes doing it like that? Is there actually a good reason to 
do so? What's the difference between "tryPost" from ISR vs. from task?

In the end, it's a port limitation that you have to have an RX thread when 
using FreeRTOS. And I must admit I didn't follow the discussion, so I don't 
know the OS the OP is using, sorry...
