Follow-up Comment #2, bug #19816 (project lwip):

Here be dragons. To stop the stack properly you need to be able to free all
its resources - all PCBs, packet queues, buffers in use, etc. 

Handling TCP sockets in a *_WAIT state is tricky too.

Doing this cleanly would be hard, doing this without increasing the footprint
for the majority who don't need it would be very challenging indeed! I think
at a minimum, and to reduce the number of race conditions to prevent, it's
best to say that you can't stop the stack if *any* sockets/PCBs are still
