You may not use a netconn from 2 different threads at the same time ->
receiving in one thread an closing from a second thread won't work
reliably.
Newer version of lwIP (CVS HEAD) have a new switch RECV_TIMEOUT (or
something like that) which enables you let netconn_recv return NULL after a
certain time of receiving nothing.
