The general idea is good, but I don't see why you need to change the lwIP 
sources for that: you'd have to re-implement read/write/close/ioctl/fnctl 
anyway to call the correct subsystem. Doing that, you can increase/decrease the 
file descriptor in a central place in these wrapper functions before/after 
calling the correct subsystem.
