That's an interesting one, and I think you're right in that it's not
been given much thought.  However, I can't think of anything that would
be particularly problematic.  I use lwIP as a shared library, so each
process has separate state (effectively its own stack), and when a
process that uses lwIP quits, everything is automatically cleared up. 
Are you using lwIP as a separate process to the application (i.e. many
tasks using a single lwIP stack)?
