What you're trying to do does not (yet) work. First, you need to enable
LWIP_NETCONN_FULLDUPLEX in your lwipopts.h, but then asynchronously closing a 
socket
while another thread is waiting for RX still does not work.

I'm at it though, check for bug #52554, which should be closed in some days (or
weeks, or months):
https://savannah.nongnu.org/bugs/?52554

Chances are high that this will work with 2.1.0, which should not be too far 
away.
