(2) I need a solution asap :) Can you suggest a class of "safe places"
to flash the lock?

   By flash I mean:

   UNLOCK_TCPIP_CORE();
   LOCK_TCPIP_CORE();
I'm afraid I can't: you'd need a mechanism to e.g. prevent the pcb you're sending on to be freed from other threads. lwIP just doesn't provide that (yet?).
