There is no safe way to do this on lwIP.  It would involve using the socket 
from two different threads and that is not supported.  The best approach is to 
set a flag when you want the thread to stop reading, and a timeout on your 
lwip_recv() operation.  When lwip_recv() times out check the flag to see if you 
should continue blocking, if so call lwip_recv() again, if not close the 
connection.
