--- Comment #36 from Bruno Jesus <00cpxxx(a)gmail.com> ---
This is a kernel trap. The game is doing setsockopt(SO_SNDBUF, 65536) but as
stated in the docs the (linux) kernel will double the value and when asked for
the size with getsockopt(SO_SNDBUF) it will return 131072. This makes the game
very sad because the comparison is probably != instead of >=

By dividing the value from getsockopt by 2 the game will be happy and will
attempt to connect to Novaworld and ask for an update. Unfortunately the ftp is
no longer active (at least for me) and then the update process will sit forever
waiting.

See SO_SNDBUF at http://man7.org/linux/man-pages/man7/socket.7.html

It's possible to fix this by storing the requested buffer size in the
wineserver socket object. Then we would do the getsockopt and return the min()
from what wineserver has and getsockopt returned.
