As I expected, this isn't allowed, either on the client end or server end of a
named pipe.  My tests that demonstrate it were sent in:
http://www.winehq.org/pipermail/wine-patches/2009-February/069264.html

This, in contrast, is possible.  I haven't tested reading and writing in this
case, just that the API to switch modes succeeds.  See the above link.

Also possible.

> message-mode on the server, and see what happens.

Not possible.  See tests.
