Are you trying to say that I did know the particular fatal issues
in the revprop caching before the 1.8 release? You are totally wrong,
if yes. Don't know if something like this is possible at Wandisco.
But this is absolutely not possible at VisualSVN.
Also, I'm not that smart, for sure. I just have had a suspicion
that something is internally wrong with that feature by looking
through your commits. That's why this feature is not enabled by
default in the product I'm responsible for. I didn't have strong
arguments against the revprop caching feature at that time.

That's great idea, thanks for investigation! But have you forgot
that revprop caching was actually disabled at the compilation time
because Windows atomics implementation were considered as
"inefficient" in 32-bit Windows builds?
As was accidently revealed unit tests for named atomics (and revprop
caching) were skipped under non-administrative account .

And what you have learned from the "revprop caching debacle"? That
Ivan and other "template zombies" behaved in the wrong way and
didn't help you to success while you are saving this project from
