This is the lwip no-os version of SO_REUSEADDR, which is set on all listening sockets in the espressif port; do so here as well, it makes running servers easier. The "address in use" error does not occur.
``` >>> s = socketpool.SocketPool(wifi.radio) >>> s.getaddrinfo("google.com", 80) [(0, 0, 0, '', ('142.250.81.206', 80))] ```
