Apparently the problem is that xnet_connect_wait_thread() expects
XNET_connect() to throw an exception upon error but for some errors,
XNET_connect() simply returns NULL.
So the solution is either to check return value for NULL in
xnet_connect_wait_thread() (as inet_connect_wait_thread() does) or throw
exception instead of returning NULL, either in XNET_connect() or as deep
as in connect_server() (in src/remote/os/win32/xnet.cpp). I'm not
familiar with the code enough to decide which option is preferrable.
BtW, the same problem is likely with wnet_connect_wait_thread() which
doesn't check return value of WNET_connect() either (but I didn't check
whether it can actually return NULL).
