This sounds *really* promising. Reading it makes me want to descale my C and
start working on it :-)

I don't understand how this is going to work. How do you want to keep track
of the times? Do you want to cycle through your cache entries slowly and
compare the cached data to the disk data? Do you want to hook into
windows-something so the cache gets notified if files / folders change?

You can stop the recursion at the point when you found the 'maximum'
dominant SVN Status for a folder. You are of course going to notice when you
are recursing into a folder that is already cached (with its dominant status
known), so you can stop there too.
Entering a folder should also propagate the status up towards the wc root
until it hits something 'stronger'

Yep, I always switch it on if I demo TortoiseSVN and tell people that it's
only usable for small projects, so they should switch it off :-|

A cached WC status tree can be 'entered' anytime at any place inside the
tree. This can help us a lot in keeping information up to date.
Just out of interest. How much memory does a cached file/folder status
