Since my VxD is independent of WSOCK and the WinSock DLL, it shouldn't
matter whether you have Winsock 1.x or Winsock 2.

No, just TCP and UDP at this time.  I'm trying to remember if the BSD
interface is complete.  I'm not sure--I think e.g. that it may be that not
everything that you should be able to make nonblocking, is able to be made
nonblocking.  Peter, do you know about this?
