I've just copied 21 Gigs from a Linux box to a WIndows box using the
exact same ssh|tar as you did.  There's nothing pointing to any kind of
memory or handle leak while doing that and the operation terminated

Are you by any chance starting the X server from a service or something?
Maybe that's a problem induced by the heap allocation as Chris has 
already noted in a few threads.  Er... lemme see...
