You mean the one where the server does ConnectPipe, then the client 
does, Open, Close, Open....  I've seen that one before, and will have a 
look at into it if Rob doesn't beat me to it.

I'd also like to make the pipes work properly in overlapped mode, and 
fix overlapped I/O on files ... but Aric wants me to do some MSI stuff 
first.  It will be a busy week :)
