Most likely not winsock. The reason for this claim ?

Well, I tried this with a dedicated Q2 server, and this one doesn't
crash, instead it reports:

    NET_GetPacket: WSAEMSGSIZE

A dedicated unreal server reports the same:

    Log: UDP recvfrom error: WSAEMSGSIZE

So it seems that winsock reports an error, but QW doesn't handle it
properly.

(All tests done on NT4/SP4).
