A wine developer clearly showed that this option simply doesn't work.

Output of strace:
getsockopt(24, SOL_SOCKET, SO_REUSEADDR, [0], [4]) = 0
setsockopt(24, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
bind(24, {sa_family=AF_INET, sin_port=htons(43012), sin_addr=inet_addr("0.     
0.0.0")}, 16) = -1 EADDRINUSE (Address already in use)

Its clear that some other socket did not use SO_REUSADDR

All sockets using a given port _must_ have use SO_REUSADDR to allow this
port being reused.

It's exactly what's been tried. A program running with SO_REUSADDR, once no longer
running consequently fails to regain the rights for the port.
