Hi Christopher,
after more extensive using, I have to notice that it's still quite a lot 
buggy. Sometimes there are parts of alternative screen in the scrollback 
buffer, sometimes for example vim hangs while starting or completely 
crashes.
You can see, that sometimes there are 2 blank lines between the prompts, 
sometimes only 1 on this screenshot: http://ferenczy.cz/tmp/cygwin/4.png
I don't know how to simulate crash, hang or scrollback buffer crippling yet, 
it seems that it happens randomly to me.
