Is the idea that the SocketImpl.getFileDescriptor would just return
null?  That seems reasonable, weirdly enough.  Or maybe we could have
it either return an invalid fd or throw some exception.

There's actually two uses for getFileDescriptor; you can call
FileDescriptor.sync or FileDescriptor.valid.  I don't find either of
these really compelling.
