AFAIK, Mac OS 9 & below is the only OS that Subversion supports/will
support that allows applications to scribble on its own memory.

 From here http://www.computeruser.com/articles/1910,5,18,1,1001,00.html
"*Protected memory - *We Mac users like to boast that our systems don't
crash as often as Windows. And (ahem) that's true, but they do
occasionally crash. And when one application goes down, your whole
system can go down in flames alongside it. That's because the current
Mac OS doesn't have protected memory. Mac OS X will."
