I have some code for the mailslot implementation, but it's weekend work 
for me.  It would be pretty easy to wrap the test in a todo_wine{} but 
we already know that none of the tests will pass, so it won't prove much.

I think I'll just wait until I have an implementation that works.  I've 
run my test on WinNT 4... if somebody felt like verifying it on Windows 
2000 and Windows XP, that could be helpful.
