Blair,

The initial patch I've submitted to this does not alter the way you've
done your exponential search and works completely within the
constraints you've set. I can easily modify your code and extend it
to do the revs/revprops check for each revision, which makes the most
sense and could then be used for 'svnadmin verify'. Do you mind
looking at the second patch I submitted to Issue 2992 and reviewing it
as-is? Once we get that patch applied, I'll expand it.

Take care,

Jeremy
