Strange - now I can't reproduce the behavior I was seeing with a single use of Yank erasing the kill ring. I'll fix that.
However, I also (at least in TextEdit) can't reproduce what you're saying about multiple consecutive kills appending text to the kill ring. Whenever I do more than one kill in a row, the last one is all that can be yanked.
