Follow-up Comment #14, patch #3796 (project lwip):
I think the best thing to do to fix this kind of problem is to move most of
the write process in tcpip_thread (in api_msg). I have submit a patch for
lwip_sendto like this for bug #19162 (I have to test it when I will come to
the office).
It will give a something more safe-thread (by example, if two application
threads want to write datas on the same socket).
To my point of view, SYS_ARCH_PROTECT should only have to be used in pbuf, &
memp functions...
