Given linux's process mode, this doesn't work: a shared library is shared code 
(constant) but not shared data. What you want is sharing data between 
processes. That won't get too easy with lwIP, I guess you will have to write a 
library interfacing lwIP, use that from your 2 processes and run lwIP as a 
server process (3rd process).
