Just in case it's helpful: Are you sure you really don't have shared 
memory, in it's most trivial meaning? You seem to have a rudimentary O/S 
which makes it unlikely that memory protection is active.

The point may be if your O/S supports multiple threads. If it does, you 
might even implement semaphores yourself, and use the multitasking API 
of lwIP.
