Again, I don't know much about X so I'm going to talk blind here....

... XWin is the X server so if xwinclip is part of XWin, then it knows 
that the server is shuting down/reseting because XWin is shuting 
down/reseting, doesn't it?

Also, I thought that the use of select() in test04 was to avoid problem 
with disconnection.
test05 changelog says that there is still a problem with GiveUp. But I 
guess that GiveUp ends up calling ddxGiveUp. Maybe this ddxGiveUp could 
be useful (like to close the X client connection if it's not too late to 
do it)

Also (it's probably more work but...) the X server is the one handling 
the clipboard, isn't it? So if xwinclip is integrated into the server, 
it should not need to be a X client anymore so no more problem with 
connections. Maybe Chris would be interested into looking into that 
(that would occupy his mind for quite a while a guess :)).
