That's true, but it depends on whether the blocking state is
transferred across a dup() call.  The file descriptor used in a dll
comes from wine_server_handle_to_fd:
http://source.winehq.org/source/dlls/ntdll/server.c#L635

I confess I don't know whether it is.  But the existence of the
do_blocking call strongly implies that it is, doesn't it?
