Yes, you could execute a process instead of a thread. However you would
then, as you realise, have to re-write the other parts of sys_arch.c to
use inter-process communication, rather than the simple inter-thread
communication that they do now. The rest of lwIP has been written not
to know or care how communication is done between the threads/processes,
so you can use whatever method you like for synchronisation.
