Think of a hosting site like sf.net with thousands of SVN repos being
hit by many thousands of users. How many of these operations do you
think the Apache server could manage before it ran out of RAM? I am
not saying we cannot ask the server to do more, but if you start
having it hang on to a list of paths, as you suggest in the rename
case, I do not see how it will not run into scenarios where that does
not involve significant amounts of memory usage.
